# Delta Drive, Delta Trust & My Drive — Storage Studio FAQ Answers about Delta X: Delta Trust, the backup vault nothing on your Mac can erase; Delta Drive, your working files on any Mac or browser; and My Drive, the same drive on storage you own — plus sharing, versions and security. ## What Delta X is - [What is Delta X in Storage Studio?](https://storagestudio.us/faq/delta-drive/what-is-delta-x) — Delta X is Storage Studio's storage family: Delta Trust for backups, Delta Drive for working files on storage we run, and My Drive for the same working drive on storage you own. Open it from More (•••) → Delta-X. - [What is Delta Drive?](https://storagestudio.us/faq/delta-drive/what-is-delta-drive) — Delta Drive is a working drive for your everyday files on storage Storage Studio runs. You can add, open, share and delete files from the Delta Drive window on your Mac, from Finder, or from any browser. - [What is Delta Trust?](https://storagestudio.us/faq/delta-drive/what-is-delta-trust) — Delta Trust is Storage Studio's backup vault on storage we run. Once something is backed up, nothing on your Mac — no program, no intruder, not even us — can delete or overwrite it for a set number of days. - [What is My Drive in Storage Studio?](https://storagestudio.us/faq/delta-drive/what-is-my-drive) — My Drive is Delta Drive running on storage you already own. It looks and works exactly the same — same screens, sharing, Finder disk and browser view — but the files live in your own storage instead of ours. - [How is My Drive different from Delta Drive?](https://storagestudio.us/faq/delta-drive/delta-drive-vs-my-drive) — Delta Drive and My Drive are the same drive with different storage behind it: Delta Drive uses storage we run and needs no setup; My Drive uses storage you own, so the account, the bill and the risk of deleting it are yours. - [What's the difference between Delta Trust and Delta Drive?](https://storagestudio.us/faq/delta-drive/delta-trust-vs-delta-drive) — Delta Trust is for backups that nothing on your Mac can delete for a set number of days; Delta Drive is for everyday files you add, share and delete freely. They're kept apart on purpose. - [Why are Delta Trust and Delta Drive kept separate?](https://storagestudio.us/faq/delta-drive/why-are-delta-trust-and-delta-drive-kept-separate) — Backups must be impossible to delete while working files must be easy to change, so Storage Studio keeps them in two halves with different protections. Changing your working drive never moves your backups. - [Where do I find Delta Trust and Delta Drive in the app?](https://storagestudio.us/faq/delta-drive/where-do-i-find-delta-trust-and-delta-drive) — Use the menu bar icon: More (•••) → Delta-X lists every Delta Trust and Delta Drive screen. Delta Trust also has its own card on the Data Backup screen, with a Delta Drive button beside it. - [Do I need my own cloud account to use Delta Drive or Delta Trust?](https://storagestudio.us/faq/delta-drive/do-i-need-my-own-cloud-account-for-delta-drive) — No. Delta Trust and Delta Drive run on storage Storage Studio looks after, so you don't need a cloud account of your own. Using your own storage is optional — that's My Drive. ## Delta Trust backups - [Does Delta Trust protect my backups from ransomware?](https://storagestudio.us/faq/delta-drive/does-delta-trust-protect-my-backups-from-ransomware) — Yes. Once backed up to Delta Trust, nothing on your Mac — no program, no intruder, not even us — can delete or overwrite it for a set number of days, so ransomware can't destroy your backup history. - [Can I or Storage Studio delete backups in Delta Trust?](https://storagestudio.us/faq/delta-drive/can-i-or-storage-studio-delete-delta-trust-backups) — No — not during the protected period. Nobody, including you and us, can delete or overwrite what's already backed up in Delta Trust for a set number of days. That's the point of the lock. - [How long are Delta Trust backups locked?](https://storagestudio.us/faq/delta-drive/how-long-are-delta-trust-backups-locked) — Each vault has a set number of protected days, shown on the Copies screen in Delta Drive. During that time nothing on your Mac — and nobody at Storage Studio — can delete or overwrite your backups. - [How do I set up Delta Trust?](https://storagestudio.us/faq/delta-drive/how-do-i-set-up-delta-trust) — Open Data Backup and follow the Delta Trust card: choose a plan, create your vault and pick where data is kept, then print your 24-word recovery kit and keep it safe. Then choose Delta Trust as a backup's destination. - [Can I choose where my Delta Trust data is kept?](https://storagestudio.us/faq/delta-drive/can-i-choose-where-my-delta-trust-data-is-kept) — Yes. Creating your Delta Trust vault includes a step where you pick where your data is kept. For extra resilience, an optional second copy can be kept with a different storage company where your plan offers it. - [How do I send a backup to Delta Trust?](https://storagestudio.us/faq/delta-drive/how-do-i-send-a-backup-to-delta-trust) — In Data Backup, open a backup card's Destination menu and pick Delta Trust — it's listed first under Included with Storage Studio, above your own drives and cloud accounts. - [Can backups go into a _Backup folder in Delta Drive instead of the vault?](https://storagestudio.us/faq/delta-drive/can-i-back-up-into-delta-drive-instead-of-delta-trust) — Yes — choosing Delta Drive as a destination puts versioned backups in a _Backup folder, opened by the same recovery kit. Unlike Delta Trust, that folder can be deleted like any other file. - [Should I back up to Delta Trust or Delta Drive?](https://storagestudio.us/faq/delta-drive/should-i-back-up-to-delta-trust-or-delta-drive) — Choose Delta Trust if you can only have one: nothing on your Mac can remove its backups. Use Delta Drive as a convenient second copy that you can see and manage — and therefore delete. - [How do I restore files from Delta Trust?](https://storagestudio.us/faq/delta-drive/how-do-i-restore-files-from-delta-trust) — Open Storage & restore on the Delta Trust card (or More → Delta-X), pick the version you want and where it should go. On a new Mac, your recovery kit opens the vault. - [Can I browse my Delta Trust backups like a drive?](https://storagestudio.us/faq/delta-drive/can-i-browse-my-delta-trust-backups-like-a-drive) — No. Delta Trust backups are deliberately impossible to browse — not on your Mac, on the web, or by us. Use Storage & restore to get files back, or keep a browsable copy in Delta Drive. - [Why are there two sets of Documents, Desktop and Pictures switches?](https://storagestudio.us/faq/delta-drive/why-are-there-two-sets-of-documents-desktop-and-pictures-switches) — Delta Trust's switches back the folders up into the vault (encrypted, versioned, not browsable); Delta Drive's switches copy the real files into your drive to open and share. They're independent — use either or both. - [Why does my Documents folder look empty in Delta Drive when it's backed up?](https://storagestudio.us/faq/delta-drive/why-does-documents-look-empty-in-delta-drive) — Backing a folder up to Delta Trust doesn't copy it into Delta Drive — vault backups can't be browsed. To see the files in your drive, press Keep a copy of my Documents here in Delta Drive. - [What is the second copy option for Delta Trust?](https://storagestudio.us/faq/delta-drive/what-is-the-second-copy-option-for-delta-trust) — Where your plan offers it, a second copy keeps your vault with a different storage company so an outage at one doesn't strand you. It's the same backup elsewhere, not a second vault, and it runs on our servers, not your connection. - [What happens when I turn off the Delta Trust second copy, and what does it cost?](https://storagestudio.us/faq/delta-drive/what-happens-when-i-turn-off-the-second-copy) — Turning the second copy off stops the charge and new writes but keeps what's there; deleting it is a separate step. While on, you pay for the space the second copy actually uses, not a flat fee. ## Security, sign-in and privacy - [Which cloud company stores Delta Drive and Delta Trust data?](https://storagestudio.us/faq/delta-drive/which-company-stores-delta-drive-data) — We don't publish which storage companies run behind Delta Drive and Delta Trust. What matters for you: you choose where vault data is kept, only your recovery kit opens it, and a second copy elsewhere is available where your plan offers it. - [Will I know if Storage Studio touches my vault?](https://storagestudio.us/faq/delta-drive/will-i-know-if-storage-studio-touches-my-vault) — Yes. Any time Storage Studio touches your vault's account it's recorded in your own Vault activity log in plain English (More → Delta-X → Vault activity). We still can't open your backups without your recovery kit. - [Can Storage Studio read my Delta Trust backups?](https://storagestudio.us/faq/delta-drive/can-storage-studio-read-my-delta-trust-backups) — No. Delta Trust backups are encrypted on your Mac and only your 24-word recovery kit opens them. We can't look up or reset that kit, so we can never read your backups. - [What is the 24-word recovery kit for Delta Trust?](https://storagestudio.us/faq/delta-drive/what-is-the-delta-trust-recovery-kit) — The recovery kit is 24 words, printed when you create your Delta Trust vault. It is the only way back in: if you lose it, your backups can never be recovered — not even by Storage Studio. - [What if I lose my Delta Trust recovery kit?](https://storagestudio.us/faq/delta-drive/what-if-i-lose-my-delta-trust-recovery-kit) — Your recovery kit is the only way back in; if you lose it, your backups can never be recovered — not even by Storage Studio. On the Mac the vault was set up on, the key button on the Delta Trust card shows the words again after a code we email you. - [Where should I keep my Delta Trust recovery kit?](https://storagestudio.us/faq/delta-drive/where-should-i-keep-my-recovery-kit) — Keep it somewhere safe and separate from the Mac it protects — a kit that lives only on that Mac is lost with it. Don't share the 24 words with anyone. - [What encryption does Delta Trust use?](https://storagestudio.us/faq/delta-drive/what-encryption-does-delta-trust-use) — We don't publish the technical details, but the promise is: backups are encrypted on your Mac, only your recovery kit opens them, and for the protected period nobody can delete or overwrite them — including us. - [How do I sign in to Delta Drive in a browser?](https://storagestudio.us/faq/delta-drive/how-do-i-sign-in-to-delta-drive-in-a-browser) — Signed in to your account on our website, Delta Drive opens without a second sign-in. Otherwise sign in with your licence email and the 12-character code we email you — copy and paste it. Two-step sign-in still asks for its code. - [Why doesn't Delta Drive have a password?](https://storagestudio.us/faq/delta-drive/why-doesnt-delta-drive-have-a-password) — Delta Drive signs you in with a one-time email code instead of a password — nothing to forget or leak. For extra protection beyond your inbox, turn on two-step sign-in with an authenticator app. - [My Delta Drive sign-in code doesn't work — what should I do?](https://storagestudio.us/faq/delta-drive/my-delta-drive-sign-in-code-doesnt-work) — Copy and paste the newest code rather than typing it — it's 12 characters and capitals matter. Each code works once for fifteen minutes. Use your licence email, check spam, and have your authenticator code ready if two-step sign-in is on. - [How do I turn on two-step sign-in for Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-turn-on-two-step-sign-in-for-delta-drive) — In Delta Drive on the web, open Security → Set it up, add it to an authenticator app and enter a working code. Then sign-in needs your email code plus the app's code. Save the recovery codes — they're shown once. - [What if I lose the phone with my Delta Drive authenticator app?](https://storagestudio.us/faq/delta-drive/what-if-i-lose-the-phone-with-my-authenticator-app) — Sign in with one of the recovery codes you saved when you set up two-step sign-in — each works once. They can't be shown again, so when you're low, turn two-step off and on to get a fresh set. - [How do I disable two-step sign-in for Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-turn-off-two-step-sign-in) — In Delta Drive's Security screen on the web, enter a current authenticator or recovery code and choose Turn off. The code is required so someone with only your inbox can't remove the protection. - [Can I see who signed in to my Delta Drive?](https://storagestudio.us/faq/delta-drive/can-i-see-who-signed-in-to-my-delta-drive) — Yes. Delta Drive's Activity screen lists sign-ins (successful and failed), uploads, downloads, deletions and shares, with the rough country and city of each — never the address itself. - [How do I lock a folder in Delta Drive with a PIN?](https://storagestudio.us/faq/delta-drive/how-do-i-lock-a-folder-in-delta-drive) — Right-click a folder in the Delta Drive window ▸ Lock…, choose a 6-digit PIN and confirm with an emailed code. It opens only in Storage Studio on your Mac — never in a browser or Finder. Forget the PIN and lose your recovery kit, and it can never be opened again. - [What if I forget the PIN for a locked Delta Drive folder?](https://storagestudio.us/faq/delta-drive/what-if-i-forget-my-delta-drive-folder-pin) — Choose Forgot PIN…, type your recovery kit's 24 words and paste an emailed code — the PIN is shown once. If you forget the PIN and lose your recovery kit, the folder can never be opened again; Storage Studio can't recover it. - [Who can open a locked folder in Delta Drive — can support unlock it?](https://storagestudio.us/faq/delta-drive/who-can-open-a-locked-delta-drive-folder) — Only someone with both your PIN and your email. Storage Studio never opens a locked folder, and our support team can't unlock one for anyone. Finder's Locked checkbox is different: it only stops accidental changes and doesn't keep anyone out. - [When does a locked Delta Drive folder lock itself again?](https://storagestudio.us/faq/delta-drive/when-does-a-locked-folder-lock-again) — After 5, 15 (the default), 30 or 60 minutes without use, and whenever your Mac sleeps, its screen locks or Storage Studio quits, or on Lock now. Files you opened from it are private copies, deleted when it locks again. ## Using Delta Drive - [How can I get to my Delta Drive files?](https://storagestudio.us/faq/delta-drive/how-can-i-get-to-my-delta-drive-files) — Three ways, all showing the same files: the Delta Drive window on your Mac (click the Delta Drive card on Home), Finder, where the drive can appear like a disk, or any browser signed in with your licence email. - [Can Delta Drive appear in Finder like a disk?](https://storagestudio.us/faq/delta-drive/can-delta-drive-appear-in-finder) — Yes — when your Mac has the software for it, Delta Drive shows in Finder like a disk. If not, Storage Studio opens its own Delta Drive window instead and says so; the files are the same. - [Can I open and edit a Delta Drive file directly?](https://storagestudio.us/faq/delta-drive/can-i-open-and-edit-a-delta-drive-file-directly) — Yes. Double-click a Delta Drive file to open it in its usual app, and your changes save back to the drive automatically. Use Save a copy… when you want a detached copy on your Mac. - [What happens if a Delta Drive file changed somewhere else while I was editing it?](https://storagestudio.us/faq/delta-drive/what-if-a-delta-drive-file-changed-while-i-was-editing-it) — Nothing is overwritten. If the file changed elsewhere while you had it open, your version is saved beside it under a name saying where it came from, and the app tells you. Both copies stay in your drive. - [How do I add files to Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-add-files-to-delta-drive) — Click Add → Files… or Folders… (or New folder) in Delta Drive, or drag files in from your desktop in a browser. Use Add → Link a folder… to keep a Mac folder feeding the drive automatically. - [Do uploads continue if I close the Delta Drive window?](https://storagestudio.us/faq/delta-drive/do-uploads-continue-if-i-close-the-delta-drive-window) — Yes. Uploads run in their own queue and keep going after you close the window. Big files go in pieces so a dropped connection resumes, and anything that keeps failing stays listed as failed. - [What are the Documents, Desktop, Pictures, Shared and Team folders in Delta Drive?](https://storagestudio.us/faq/delta-drive/what-are-the-starting-folders-in-delta-drive) — Every Delta Drive starts with Documents, Desktop and Pictures (matching your Mac's folders), Shared (things sent to you) and Team (for your organisation). These five can't be removed. - [Why can't I delete the Shared, Team or Documents folder in Delta Drive?](https://storagestudio.us/faq/delta-drive/why-cant-i-delete-the-shared-or-team-folder) — The five starting folders can't be removed because backups and shares point at them, but their contents can. Right-click one and choose Empty this folder… to move everything inside to the trash. - [What happens when I delete something in Delta Drive?](https://storagestudio.us/faq/delta-drive/what-happens-when-i-delete-something-in-delta-drive) — Deleting moves it to Delta Drive's Trash, on your Mac and the web, after showing what will go. Same-named items binned on different days are kept separately, and anything can be put back. - [Does the Delta Drive trash empty itself?](https://storagestudio.us/faq/delta-drive/does-the-delta-drive-trash-empty-itself) — No. Items in Delta Drive's Trash never expire on their own and count towards your storage until you remove them with Delete for good or Empty trash. - [How do I restore something from Delta Drive's trash?](https://storagestudio.us/faq/delta-drive/how-do-i-restore-something-from-delta-drive-trash) — Open Trash, right-click the item and choose Put back. It returns to its folder and never overwrites anything — a same-named item comes back as name (2), and a missing folder is made again. - [What do the little marks next to files in Delta Drive mean?](https://storagestudio.us/faq/delta-drive/what-do-the-marks-next-to-files-in-delta-drive-mean) — The marks show where a file is and who can see it: Online only, Ready to read, Always on this Mac (hollow while arriving), Shared, Versions kept, Linked and Comments. Hover one for its meaning. - [What does 'Last heard' mean on a Delta Drive file?](https://storagestudio.us/faq/delta-drive/what-does-last-heard-mean-on-a-delta-drive-file) — Last heard means the Mac holding that offline or cached copy hasn't checked in for a couple of days, so Delta Drive can't confirm the copy is still there. Opening Storage Studio on that Mac updates it. - [What keyboard shortcuts work in Delta Drive?](https://storagestudio.us/faq/delta-drive/what-keyboard-shortcuts-work-in-delta-drive) — Press ⌘/ in Delta Drive for the full list. Handy ones: ⌘↓ open, ⌘↑ up, ⌘T folder tree, ⌘F search, ⇧⌘S share, ⌘K versions, ⌘⌫ trash, ⌘N new folder, ⌃⌘1–3 change view. - [How do I change the view or sort order in Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-change-the-view-or-sort-order-in-delta-drive) — Pick Icons, List or Details in Delta Drive (it remembers your choice) and use Sort by for Name, Kind, Size or Date modified — choose it again to reverse. Folders always sort first. - [How do I jump between folders quickly in Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-jump-between-folders-quickly-in-delta-drive) — Click any step of the breadcrumb trail at the top, or press Folders (⌘T) for a folder tree. Clicking My Drive again takes you back to the top. - [How do I move or copy files in Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-move-or-copy-files-in-delta-drive) — Drag items onto a folder to move them, or hold Option as you drop to copy. Right-click for Rename and Get info; in a browser you also get Cut, Copy, Paste and Move to…. - [How do I pin a folder to the Delta Drive sidebar?](https://storagestudio.us/faq/delta-drive/how-do-i-pin-a-folder-to-the-delta-drive-sidebar) — In a browser, right-click a file or folder and choose Add to favourites. Favourites belong to the drive, so they follow you to any browser and keep working when the item is moved or renamed. - [How do I see details about a file in Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-see-details-about-a-file-in-delta-drive) — Select an item and choose Get info (or press space) to see its location, size, last change, whether it's kept on this Mac, any linked Mac folder, and links to versions and comments. Folders show no size. - [Can I view Delta Drive files in my browser without downloading them?](https://storagestudio.us/faq/delta-drive/can-i-view-delta-drive-files-in-my-browser) — Yes. Click a file on the website and it opens in the browser — pictures, PDFs, video, audio, text and code, Markdown, JSON, spreadsheets as tables, Office documents and archives — with search, print and full screen. ## Delta Drive on your Mac - [How much of Delta Drive is stored on my Mac?](https://storagestudio.us/faq/delta-drive/how-much-of-delta-drive-is-stored-on-my-mac) — You choose from the gear menu: Always keep on this Mac (per folder, works offline), Keep a copy while I'm using it (files you open stay a day up to ninety days and reopen at once), or Online only (no disk used). - [How do I keep a Delta Drive folder available offline?](https://storagestudio.us/faq/delta-drive/how-do-i-keep-a-delta-drive-folder-available-offline) — Right-click the folder and choose Always keep on this Mac. A full copy stays on your Mac (or your fast drive), kept up to date, and opens with no network. - [How do I clear Delta Drive's copies from my Mac?](https://storagestudio.us/faq/delta-drive/how-do-i-clear-delta-drive-copies-from-my-mac) — Use the gear menu's Delete downloaded copies from this Mac in Delta Drive. It removes the copies kept on your Mac without deleting anything from the drive; files come back when you open them. - [Delta Drive looks out of date or a folder is missing — what can I do?](https://storagestudio.us/faq/delta-drive/delta-drive-looks-out-of-date-or-missing-a-folder) — Delta Drive refreshes a folder older than a minute when you return. Otherwise use the gear menu: Reload what's on screen, Delete downloaded copies from this Mac, or Recreate anything missing… — which never deletes a backup. - [Why does Delta Drive show my folder straight away and then update it?](https://storagestudio.us/faq/delta-drive/why-does-delta-drive-show-an-older-folder-first) — Delta Drive shows the folder you last saw at once, then checks it with the drive. Returning to the window refreshes a folder older than a minute, so changes from the web or another Mac appear by themselves. - [Why did my Finder favourite to Delta Drive stop working after I switched drives?](https://storagestudio.us/faq/delta-drive/why-did-my-finder-shortcut-to-my-drive-stop-working) — The Finder folder is named after your active drive — Delta Drive, or My Drive and your storage's name — so a favourite or alias to the old name stops working after a switch. Nothing moved; make a new favourite. ## My Drive — storage you own - [How do I use my own cloud storage with Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-use-my-own-cloud-storage-with-delta-drive) — Choose Delta Drive → Storage → Connect storage you own…, then enter your bucket, region and access keys. Storage Studio tests a write before saving, and the drive becomes My Drive with the same screens. - [Will My Drive touch other files in my storage bucket?](https://storagestudio.us/faq/delta-drive/will-my-drive-touch-other-files-in-my-bucket) — No. My Drive reads and writes only under one prefix inside the bucket you name, so everything else there is untouched — and removing the drive only deletes inside that prefix. - [Why was my storage refused when I tried to connect My Drive?](https://storagestudio.us/faq/delta-drive/why-was-my-storage-refused-when-connecting-my-drive) — Storage Studio writes and deletes a test file before saving, and shows your provider's own refusal if that fails. Check the bucket name, region and keys, and make sure the keys can write and delete. - [Are my storage keys safe with My Drive?](https://storagestudio.us/faq/delta-drive/are-my-storage-keys-safe-with-my-drive) — Yes — My Drive stores your access keys encrypted and never shows them back to anyone, including you and us. Limit the keys to the bucket My Drive uses. - [Is My Drive as safe as Delta Trust for backups?](https://storagestudio.us/faq/delta-drive/is-my-drive-as-safe-as-delta-trust-for-backups) — No. Anything holding your keys can delete what's in My Drive. Delta Trust holds a credential you don't have, so nothing on your Mac can erase it — keep it for backups that must survive a bad day. - [Does My Drive keep file history when I use my own storage?](https://storagestudio.us/faq/delta-drive/does-my-drive-keep-old-versions-of-my-files) — Only if you've turned versioning on with your own storage provider — it affects their bill, so Storage Studio won't switch it on. The Versions screen tells you which setting it found. - [Can I switch between Delta Drive and My Drive?](https://storagestudio.us/faq/delta-drive/can-i-switch-between-delta-drive-and-my-drive) — Yes. Make another drive active from the Viewing picker or Storage — it asks first, and if anything fails the switch is undone. Nothing is copied or deleted, and your Macs and the website follow the active drive. - [What happens when I switch off Delta Drive or My Drive?](https://storagestudio.us/faq/delta-drive/what-happens-when-i-disconnect-my-drive) — Switch off asks first and deletes nothing — files, folders and settings stay as they are, and an Undo appears straight after. Nothing opens until you choose Reconnect, which needs nothing set up again. - [Can I view Delta Drive in a browser while my Mac uses My Drive?](https://storagestudio.us/faq/delta-drive/can-i-view-delta-drive-in-a-browser-while-my-mac-uses-my-drive) — Yes. The website's Viewing picker changes only what that browser shows; your Macs keep using the active drive. On the Mac, the Viewing picker opens any other drive in your browser without changing anything. - [Do my Delta Trust backups move if I switch to My Drive?](https://storagestudio.us/faq/delta-drive/do-my-delta-trust-backups-move-if-i-switch-to-my-drive) — No. Delta Trust stays where it is whichever working drive you use — switching between Delta Drive and My Drive never moves or replaces your backups. ## Linked folders and copies - [How do I keep a copy of my Mac's Documents folder in Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-keep-a-copy-of-my-documents-folder-in-delta-drive) — Open Documents, Desktop or Pictures in Delta Drive and press Keep a copy of my Documents here (also on the right-click menu and Copies screen). It's then kept up to date; turning it off leaves the copy in place. - [How do I link any folder on my Mac to Delta Drive?](https://storagestudio.us/faq/delta-drive/how-do-i-link-a-folder-on-my-mac-to-delta-drive) — Choose Add ▸ Link a folder…, pick a folder on your Mac, name it in your drive and choose online only, offline only, or both in sync. You can change the mode later without deleting anything. - [What's the difference between online only, offline only and both in sync for a linked folder?](https://storagestudio.us/faq/delta-drive/what-is-the-difference-between-linked-folder-modes) — Online only keeps files in Delta Drive and frees your Mac; offline only keeps them on your Mac and never uploads them; both in sync keeps a full copy in each place, using the space twice. - [Does 'Available offline only' upload my files to Delta Drive?](https://storagestudio.us/faq/delta-drive/does-available-offline-only-upload-my-files) — No. Offline-only folders are never uploaded — Delta Drive learns only names, sizes and dates so you can see what's there. The contents stay on your Mac and are reachable only while it's on. - [If I delete a file on my Mac, is it deleted from Delta Drive too?](https://storagestudio.us/faq/delta-drive/if-i-delete-a-file-on-my-mac-is-it-deleted-from-delta-drive) — No. Linked folders go one way, Mac to drive: deleting on your Mac doesn't delete from Delta Drive, and Delta Drive never changes your Mac's folder. Delete it in Delta Drive if you want it gone there too. - [What happens when I unlink a folder from Delta Drive?](https://storagestudio.us/faq/delta-drive/what-happens-when-i-unlink-a-folder) — Unlinking forgets the connection and deletes nothing on either side. If the Mac folder disappears (say, an unplugged disk), the link stays and says so, and the drive copy is untouched. - [Why won't Delta Drive let me link a folder?](https://storagestudio.us/faq/delta-drive/why-wont-delta-drive-let-me-link-a-folder) — A link is refused when its name is already used in your drive, you picked a file, the folder is already inside Delta Drive, or it's already linked under another name. Fix that and try again. - [How do I see how many copies of my data exist and where?](https://storagestudio.us/faq/delta-drive/how-do-i-see-how-many-copies-of-my-data-exist) — The Copies screen in Delta Drive shows your main copy's size and lock days, whether a second copy is on, and every Mac folder kept in the drive with its status and a Copy now button. - [What is a synced folder in Delta Drive, and how is it different from a linked folder?](https://storagestudio.us/faq/delta-drive/what-is-a-synced-folder-in-delta-drive) — A synced folder keeps a folder on your Mac and one in your drive the same — Both ways, Mac → Drive or Drive → Mac. Anything a sync removes goes to a Trash, never erased. When both sides changed a file, Newer wins by default, or choose Keep both. - [Why did my synced folder stop and turn orange?](https://storagestudio.us/faq/delta-drive/why-did-my-synced-folder-stop-and-ask) — A sync stops before a big delete — over 50 files, over a fifth of the folder, or every file changed at once.
