Relocate big apps and folders to a fast external drive — a shortcut stays behind at the original path, so Finder, Spotlight, and your apps open everything as if nothing moved. Fully reversible, with one-click undo.
The heart of Storage Studio
Tuhi clears caches and rarely-used files and reclaims old local backups, while App Offload parks apps you barely use — and their data — on the drive to free the most space. Every step previews first; nothing personal is removed without asking.
Tuhi · App Offload · preview-first
Ask anything about your storage in plain English — "what's using my space?", "how do I sync to S3?" — and Tuhi answers, then takes you to the right screen. It runs entirely on your Mac with Apple Intelligence, so your files and questions never leave the device.

Carry the drive, not the workflow.
Auto-thinning makes Move-to-NVMe actually free your boot disk in real time — which makes "use NVMe as a permanent second volume" finally practical. Pair a small USB-C / MagSafe-attached / Thunderbolt enclosure with Storage Studio and treat your boot disk like cache: working set on internal, archive on NVMe, both always one click apart.
Illustrative — Storage Studio is a software product, we don't ship hardware. Any APFS-formattable USB-C / Thunderbolt enclosure works.
A 1–2 TB USB-C stick or magnetically-attached enclosure travels with the laptop. Pull it off when you don't want it; reattach and it's mounted in seconds.
A Thunderbolt enclosure stays plugged in and inherits your workflow — perfect for the Mac mini / Studio crowd.
Move the same NVMe between a personal MacBook and a work iMac. Storage Studio recognises the marker file and re-pairs without a re-setup.
When other tools archive a file, they lose its dates, tags, and provenance. Archiving in Storage Studio keeps the full file identity intact — including the three dates most tools silently rewrite during the move.
Delta Trust
Delta Trust is the backup part of Delta X — Storage Studio’s storage side, which is Delta Trust for your backups, Delta Drive for your working files, and My Drive when you would rather those working files sat on storage you already own. We run the storage here; you hold the keys. It is built around the three questions that decide whether a backup was worth keeping — can anyone else read it, can an attack destroy it, and can you still get back the version you need.
Only you can read your backups. Your files are encrypted on your Mac before they leave it, with a key we never see. We can close your vault; we can never open it.
Encrypted before it leaves your Mac
Nothing on your Mac can delete your backups. Even if your Mac is fully compromised, your history cannot be destroyed for 30 days — by anyone, including us.
30 days of protected history
Every version you kept is a version you can restore. Nothing — an attacker, a lapsed subscription, or us — can remove one sooner than your policy says it goes.
Restore any version you kept
Every time we touch your vault’s account, you can see it — it is written into your own activity log, in plain English. Your recovery kit is the one thing we cannot replace, so keep a copy of it somewhere safe.
If any of these describe a Tuesday afternoon for you, Storage Studio was made with you in mind.
Photoshop, Illustrator, Sketch, Figma exports, Adobe scratch files — all piling up on your boot disk. Storage Studio moves the old projects out and keeps the active ones close.
Raw footage, Reels stock, B-roll, podcast audio. Keep this month's shoot on the internal drive; let last quarter's footage live on the external. One tidy library, two drives.
Final Cut libraries, Premiere caches, DaVinci Resolve renders. Storage Studio handles the heavy hitters so your edit timeline doesn't stutter when your boot disk is full.
Years of slides, PDFs, board decks, contracts. The recent stuff stays one click away in Spotlight. The 2019 archive moves to the external — same folder, smaller boot drive.
Xcode DerivedData, Docker images, node_modules, build caches. Optional one-click cleanup for the usual suspects, and a way to move big apps off the internal drive while they keep launching normally.
MacBook Air with 256 GB? An iCloud Drive that's been quietly bloating? Storage Studio gives you the next few years of room back, without making you read a manual.
Storage Studio lives in the menu bar. It only talks to you when something needs your call — and even then it shows you exactly what it'll do before it does it.
A built-in assistant, powered by Apple Intelligence, answers your storage questions in plain English and points you to the right screen. It runs entirely on your Mac — your files and questions never leave the device.
Tell Storage Studio: 'this folder on my Mac matches that folder on the external drive.' From then on, it keeps both sides organised the way you arranged them.
A side-by-side window shows the internal and external folders together. Hover on one side and the other follows along — like a Finder window that knows about both drives at once.
Three friendly steps: clear out caches and junk, send oversize files to the external drive, and (optionally) push iCloud / Dropbox / Drive files back to online-only. Each step previews everything first.
Photoshop, Final Cut, Xcode — apps that take 5–15 GB each. Move them out and they still launch as if nothing changed. Offload the ones you rarely use to park the app and its data on the drive and free the most space, restorable in a click. Or uninstall cleanly, leftovers and all.
A clean chart of how your storage has changed over the last week, month, or year. Drag to zoom, hover to see exact numbers. Useful for explaining the disk situation to IT or the boss.
Camera or microphone in use? Storage Studio pauses everything heavy. Your Zoom call, your podcast, your client demo — never interrupted by a sync. (We don't read or record any audio or video — we just notice the Mac is busy.)
Google Drive, Google Photos, S3 (AWS, Cloudflare R2, Backblaze B2, Wasabi, DigitalOcean Spaces, MinIO), FTP, SFTP, Dropbox, OneDrive, Box. Add an account once and it shows up in every transfer picker — including cross-provider moves like S3 → SFTP or Drive → FTP.
Run a transfer every night at 2 AM, every Sunday, every hour — whatever rhythm suits you. Jobs park when the NVMe is unplugged and resume on their own when you reconnect. No cron, no scripts, no Terminal.
USB-C, Thunderbolt, the cheap 1 TB SSD you bought on a whim — they all work. Even a second folder on your Mac works if you don't have an external yet.
Maybe your Documents folder on the Mac matches an "Archive" folder on the external. Maybe it's a Movies folder. You decide — Storage Studio just remembers the pair.
Big files? Old files? Specific kinds, like raw video or PSDs? You choose. Storage Studio asks before it does anything, so nothing leaves the boot drive without your nod.
Your folders look identical in Finder. Apps open the same way. Spotlight finds everything. The only thing different is the extra hundreds of gigabytes free on your Mac.

Set it up in Storage Studio under Backup. A vault belongs to your licence and your Mac, so it is created from the app rather than bought here.
No. Storage Studio doesn't upload your files anywhere. Everything stays on your Mac and on your external drive — we never see your photos, videos, documents, or anything else.
So it can pause heavy work while you're on a video call. Storage Studio just checks whether the camera or microphone is being used — it never reads or records what's going through them.
Storage Studio always asks before it deletes or overwrites anything. There's a confirmation step on every move, and the 'Relocate' option leaves a placeholder in the original spot so files never just disappear from your folders.
15 days, no payment method needed. After that, you can buy a plan to keep going. The trial is tied to your Mac, so reinstalling the app doesn't reset it.
Nothing. Your files stay exactly where they are on both drives. Storage Studio just stops moving new things — it never holds anything hostage or makes you re-import files to use them.
Your choice. Lifetime is one-off ($249) and includes all future updates. Monthly ($9.95/mo) and Annual ($90/yr) are recurring subscriptions through Stripe — cancel anytime in the Stripe Customer Portal and access continues until the end of the paid period.
Nine, plus your local disks and any external drives: Google Drive, Google Photos, S3-compatible (AWS, Cloudflare R2, Backblaze B2, Wasabi, DigitalOcean Spaces, MinIO), FTP, SFTP, Dropbox, OneDrive, and Box. Each is added once in Cloud Accounts and then appears in every transfer picker — including cross-provider moves like S3 → SFTP or Drive → FTP. Passwords and access keys live in an AES-GCM vault on your Mac, keyed to this machine; we never see them.
All payments are final and non-refundable once you activate the app — this is why we offer a full 15-day free trial first. You can cancel a Monthly or Annual subscription anytime via the Stripe Customer Portal; future charges stop and your access runs until the end of the period already paid for. Statutory consumer rights (EU/UK 14-day right of withdrawal where unwaived, Australian Consumer Law, etc.) are preserved — contact us with your Stripe receipt and the legal basis. Full text in our Terms of Service, §5.5 and §5.6.
Unify your Mac, drives, cloud, and devices into one space; move, sync, and share without limits — and undo anything. Storage Studio runs the housekeeping so you never think about where things live. You just focus on your work.
Activate the code from your card — no payment, nothing to install first. Enter your code and a few details from your receipt and we'll email you a license to use in the app.
