Install Storage Studio
in four steps.

Every feature, grouped by what it does for you

Storage Studio isn't a cleaner — it's a platform for all your storage. Everything it does ladders up to four ideas: your storage as one space, an assistant that manages it for you, a link between your devices, and a promise that every action can be undone.

I · One space, everywhere

Your Mac, your external drives, and your cloud become a single space that's bigger than any one disk — move things around freely, and everything keeps working.

Data Parking

Browse both drives as one logical view

Two-pane file browser with mirror-hover, side-specific home buttons, and pair-relative navigation. Selecting a folder on the internal SSD auto-scrolls the external fast-drive pane to the matching folder.

Move and Merge actions preview every byte before they touch disk. Relocate leaves a shortcut behind so apps still find their files. Loop detection prevents self-overwrites. Recent pairs are pinned and survive eviction so your common workflows stay one click away. Every folder shows what it really holds, measured quietly in the background so the list fills in without ever slowing you down — and either side sorts by size, name or date, so the biggest thing is one click away.

Apps

Move, offload, uninstall — and launch — every app

An All Apps view shows every application on your Mac and on your fast drive in one tidy grid. Type to search and press Return to open it — or keep Storage Studio in the Dock and summon the grid with a keyboard shortcut.

Move a large app to your external fast drive and, with that drive connected, it still launches normally from Applications. Offload an app you rarely use to park it and its data safely on the fast drive — it frees the most space of any option, and you can restore it in one click. Uninstall removes an app and cleans up the leftover files it scatters around, moving everything to the Trash so nothing is lost; apps installed by the system simply ask for your password or Touch ID first. Apps that can't be safely relocated are clearly marked and left exactly where they are. Apps that update themselves — browsers, Electron editors and chat apps — keep working too: when one reinstalls itself, Storage Studio re-applies the move automatically while your drive is connected.

Cloud Drive

All your clouds, as one drive in Finder

Turn every connected account into a single Storage Studio drive in Finder — each cloud, plus your external working folder, a folder inside it. Browse and edit like a normal disk; changes upload on their own.

One switch mounts it; one switch removes it. A per-account list lets you choose exactly which clouds show up inside the drive. There's nothing extra to install — no kernel extension. It's built to stay put: the drive keeps running when you quit and reopen the app, and any account that's briefly offline is skipped so one unreachable cloud never stops the rest. A Remount / Repair button rebuilds it instantly after a network drop. Want a real working drive on storage you already pay for? My Drive points one at your own Amazon S3, Cloudflare R2, Wasabi or other S3-compatible bucket — included with every trial and licence — and it opens in Finder, in any browser, and shares with the people you choose.

II · Intelligent & autonomous

Tuhi and safe automation manage your storage for you — watching pressure, advising in plain English, and reclaiming what's safe. Cleanup lives here as one capability, never the headline.

Home

Open the app and know exactly where you stand

The new default view leads with a plain-English verdict — "Your Mac's storage is more than enough for now" — the Tuhi Ask box, and one tap to set everything right. No dashboards to decode.

Below the verdict, Run Tuhi clears caches and rarely-used files, reclaims old local backups, and keeps cloud files online-only — all on its own, with live progress. A live status line, storage gauges for your Mac and external drive, and at-a-glance stats (last clean-up, next clean-up, freed all-time, automatic rules) round it out, alongside a storage-over-time chart and a "More you can do" strip — Manage Apps, What's Using Space, Data Parking, Data Transfers and Usage Over Time. A banner offers a one-click Grant Access if Full Disk Access isn't on yet.

✦ Tuhi · Powered by Apple Intelligence

Ask anything about your storage

A conversational assistant, powered by Apple Intelligence, that runs entirely on your Mac. Ask in plain English about your storage and Tuhi answers — then takes you to the right screen.

Ask about your free space, any Storage Studio feature, your cloud accounts (iCloud, Dropbox, Google Drive, OneDrive, Amazon S3 and compatible services, FTP and SFTP), or general Mac storage. Tuhi can even look at your Mac's live memory, processor and temperature to help with "why is my Mac slow, hot, or low on memory?". It answers from your Mac's real storage — never guesses your numbers, never shows technical details — and guides you, step by step, to the screen that helps. Everything stays on your device.

Auto rules

Automation that fits your Mac

Storage Studio builds its automatic rules around the apps you actually have. The safest, regenerable caches are kept tidy on their own; anything less obvious is suggested for your approval — never run behind your back.

Instead of a fixed list, Storage Studio discovers the caches your installed apps create, so a newly-installed app is covered without you touching a thing. Open the Auto rules tile to see what's handled automatically and review suggestions — each showing what it is, why it's safe, and how much it would free. Approve what you want, dismiss the rest, or switch to "suggest only." Your own rules stay separate and are never changed, and nothing personal is ever deleted — only regenerable caches run automatically, everything else is moved (reversibly) and only after you say so.

Storage Inspector

Find the bytes, move them, watch them go

Scrollable leaderboard of your biggest space-hogs with a click-to-move action — and a right-side Relocated panel that lets you move folders back, delete broken relocations, or force-merge with a single toggle. Live progress with bytes / rate / ETA and the file path currently being copied.

Pre-flight surfaces every app holding the folder open with Quit-all and Recheck buttons. System background processes (Spotlight, Time Machine, and macOS's own iCloud housekeeping) are filtered out so you only see what you can actually quit. Sparse-file aware — VM images and pre-allocated databases stay sparse on your fast drive. Failed moves auto-clean their partial output so your drive never accumulates ghost folders.

Usage over time

See exactly where the bytes went

Drive-usage history with 17 selectable time ranges, dual-axis (internal SSD + external fast drive on one chart), drag-to-zoom, hover tooltips with byte-accurate readouts.

A daily snapshot is recorded on your Mac — never uploaded. Stack-chart, area-chart, and line-chart modes. Pause-and-export for support tickets. The same chart appears on Home and in Preferences so you can see how your space has trended at a glance.

Preferences

Tune the app to your workflow

Per-cloud-provider toggles, smart-mode that pauses heavy actions during camera/mic use, launch-at-login, schedule cadence, and a self-backup pane that preserves your config across reinstalls.

Smart-mode only checks whether your camera or microphone is in use — your audio and video are never accessed. Per-cloud toggles let you opt in to evicting iCloud while leaving Dropbox local, or vice versa. Self-backup saves a snapshot of your settings and recent pairings to the external fast drive.

Menu bar

Always-on status, never in the way

Lives in your menu bar. A coloured dot tells you free-space status at a glance — green, yellow, red, never modal.

Clicking the menu bar icon opens a popover with current free space on both drives, the next scheduled run, recent activity, and one-tap shortcuts to Tuhi, the Data Parking window, and Preferences. No dock icon, no main window unless you ask for one.

Reclaim & optimize · Run Tuhi

One tap to reclaim space — safely, preview-first

Run Tuhi is the one-tap way to reclaim room: it surfaces what needs attention, clears caches and rarely-used files, reclaims old local backups, and keeps cloud files online-only — automatically, with live progress. Want to drive it yourself? The advanced wizard previews every step before a single byte moves.

Run it from Home and it just works. Or open the step-by-step wizard: it surfaces caches and large files you can relocate, and can optionally move cloud files (iCloud Drive, Dropbox, Google Drive, OneDrive) back to online-only — and nothing happens without your explicit OK on the preview. Either way it's safe and reversible, and it only ever touches things you've approved.

Reclaim & optimize · Local Snapshots

Free up the space your last move was supposed to free

macOS holds on to the space deleted files used in local snapshots until they age out — so after a 90 GB move to your fast drive, your boot disk often looks barely changed. Storage Studio's snapshot manager surfaces every snapshot, tells you which ones are already on Time Machine, and reclaims the space with one click.

Per-snapshot status icons (green for backed up, amber for local only, gray for system-required) make the safe-to-delete decision visible at a glance. A reclaim banner sums the space your past moves should have freed and offers a one-button "Reclaim N GB". Custom-amount reclaim for specific targets (e.g. ahead of a macOS update). After every move to your fast drive, Storage Studio also clears just enough so the freed space shows up immediately — no waiting 24 hours for the snapshot to age out.

Reclaim & optimize · Duplicates

Find the exact copies quietly eating your space

The same download, photo or export ends up saved in a dozen places over time. Storage Studio finds files that are exact copies of each other — matched by content, not just name — and lets you keep one of each and send the rest to the Trash. It even marks the copy you're most likely using, so a whole list clears in one confirmed click. Everything is reversible.

Every place is checked independently: this Mac, iCloud Drive (only files already downloaded — nothing is pulled from the cloud to compare), and each cloud account you've connected, labelled with its real provider. Each account gets its own scan, its own progress and its own results, so one never holds up another — and results appear as they're found, so even an account with hundreds of thousands of files starts showing duplicates within about a minute. Scanning this Mac waits until it's idle, on power and cool, because reading a whole disk competes with your work; checking a cloud account is far lighter — a list of file fingerprints over the network, nothing downloaded — so it just waits for a pause in your typing. When it's waiting rather than working, it tells you why, so a quiet background scan never looks broken. Results are remembered between launches, so the window opens instantly. With Apple Intelligence on your Mac, a plain-English overview sums up what was found and how much can be freed. For every duplicate set, Storage Studio recommends the safest copy to keep — the one in a working folder, or the one you opened or created most recently — and explains why; "Clean all — keep the best of each" applies that across the whole list at once. Files that only look identical because they share storage on disk (copy-on-write clones and links) are shown separately and left alone, because removing them wouldn't free anything. Duplicates can be cleared everywhere — this Mac, iCloud, and your cloud accounts — and before you remove anything you can click a copy to open it and click its folder to go straight there, in Finder or on the provider's own website. Two files with the same name and size is exactly when you want to look first. Prefer hands-off? Let Smart Care clean duplicate files is on by default, so after its normal safe run Smart Care offers to tidy them for you — and you still approve before anything moves.

✦ Storage Profile · Powered by Apple Intelligence

Storage DNA — read on your Mac, by Tuhi

One screen tells the story of your Mac: the kind of Mac it is, the files you actually work on, your biggest space-users, and how your space splits across this Mac, your drives and the cloud. Tuhi turns it into plain English and the single most useful next step.

Biggest space-users are measured by the room they actually take up on disk — files already online-only aren't counted, so the list reflects what's really using your Mac. Free an iCloud file's local copy in one tap (it stays in the cloud). And Storage Studio stays out of your way: it caps itself to a small share of your Mac's processor and memory, indexes the way Spotlight does — quiet when you're busy, quicker when you're idle — and eases off and pauses its background work automatically when your Mac is under pressure, resuming on its own. Everything is measured on your Mac; nothing personal leaves it.

Emergency Space · where did it go?

Out of room? Emergency Space gets it back

Free space can vanish overnight with nothing to show for it. Storage Studio notices while it's happening, tells you roughly how many days of room you have left at that rate, and names the app responsible when it can — and says so plainly when it can't. It also measures the areas your Mac treats as temporary, which nothing shows you and where an app can quietly leave behind a very large share of your disk.

Drag across any drop on your storage chart and get that exact period explained: what grew, what was freed, and how much couldn't be accounted for — shown as its own line, never quietly spread across the rest. Space your Mac is holding in its own automatic backups is named rather than left unexplained, with the action that releases it beside it. That answers the question every Mac owner has asked: why deleting files sometimes frees nothing. When room runs out, say how much you need and Storage Studio proposes the smallest, safest set of steps that gets you there — safest first, with rebuildable caches and abandoned temporary files offered ahead of anything of yours, and nothing destructive ever ticked for you. A clear-up can be stopped at any point: it finishes the folder it's on so nothing is left half-removed, tells you what was done and what's left, and carries on later rather than starting again. You can see the full list of what it removes before, during and after, and everything removed stays recoverable. Afterwards you get an honest report of what actually came back, measured — not what was hoped for. It audits its own footprint first, too: a tool that frees up space has no business quietly taking it.

What's Using Space · Measured, not guessed

See what's really on your disk — then move it on your terms

Every figure is measured on your Mac, never estimated — and where something genuinely can't be measured, you're told so instead of being handed a guess. See what grew since last time, open any folder down to whatever depth it takes to find the real culprit, and read how much your Mac's own backups are holding, and how old it is.

Nothing moves until you've seen it. Everything you select is opened up with the real size of what's inside, so you approve what will actually happen rather than a summary of it. If an app is holding a folder open, you're shown exactly which one and offered to ask it to quit politely — your files stay put until you decide, and you're offered a one-click way to reopen anything that was closed. While it runs you get space genuinely returned, measured on disk, and a time estimate phrased the way a person would say it — or an honest "working out how long that will take" instead of a number it would only have to take back. And a move stays reversible for as long as your drive is connected: your folder keeps working because a link is left in its place, but the files themselves now live on the fast drive — which is precisely why the space came back.

Emergency Space · when the disk is full

Out of room right now? Start here

When your disk is nearly full, Storage Studio shows exactly what is using it and offers the safest options first — clearing files your apps rebuild by themselves, before it ever suggests moving anything of yours. Tell it how much room you want and it picks the smallest set that gets you there, and nothing happens until you choose.

Every option says what it will free and whether it can be undone, and you can open a folder to see inside before agreeing to anything. Nothing that removes data is ever ticked for you. It also explains the part most tools leave out: space your Mac is holding in its own automatic backups, which is why deleting files sometimes gives nothing back — and offers to release it. A clear-up can be stopped at any point. It finishes the item it is on, tells you what was done and what is left, and carries on later rather than starting over. You can see exactly which folders were removed, and everything it clears stays recoverable. Folders holding an app’s settings, sign-ins or history are never offered — only the parts an app rebuilds by itself.

Support · Talk to a human

Reach a real person without leaving the app

Need help? Just ask Tuhi to "contact support" — or open the menu — and a ticket opens, pre-filled and fully editable. You see exactly what will be sent, and nothing leaves your Mac until you tap Send.

Choose what to include with simple toggles — your app and macOS versions, and an optional, redacted diagnostics summary you can preview first. Your file names and contents are never part of a ticket. When Tuhi can't solve something, it offers to open a ticket for you, pre-filled with the useful details. Track everything in My Support: read the whole conversation, reply, close or reopen a ticket, and rate the experience once it's resolved. Replies arrive by email and thread right back into the app, and the team always appears simply as "Support Team" — never a personal name or address.

III · Connected & collaborative

Storage Studio is the fabric between your machines — Mac and Windows. Send files and clipboard between devices, and mirror a shared folder between two Macs.

Bridge · Mac and Windows

Connect another device — directly, privately

Bridge does two things between your paired devices: it shares another device's folders straight to your Mac, where they appear right alongside your clouds, and it shares your clipboard both ways — what you copy on one device turns up as a scrap in the other's Junk Yard. Install the free companion app on your Mac or Windows PC, type the connecting code it shows, and you're linked — over a direct, end-to-end-encrypted connection. It's a private tunnel between just your two devices, like a personal VPN: no server, no cloud; your files and clipboard never pass through anyone else's machines.

The companion app is free — Mac and Windows now, Android and Linux coming later — so your PC joins the same private space, not just other Macs. It works on the same Wi-Fi and across the internet, with a six-digit Tunnel Code shown on both ends so you know you're linked to the right device. Prefer to keep everything in the house? A local-network-only mode keeps the link entirely on your Wi-Fi, never touching the wider internet. Shared folders show up inside the Storage Studio drive in Finder, named after the device. Choose how long to stay connected — from minutes up to a week, or always — and pause, resume, or forget a device any time. Pause keeps the link warm rather than dropping it: data stops flowing but the connection stays alive, so resuming is instant and both ends clearly show who paused. A quiet heartbeat every few seconds means each side always shows when it last heard from the other. Each end also shows the other's version and offers to update when a newer Bridge is out — nothing installs on its own. Bridge can be turned on or off, and you can connect up to five devices. A dedicated Activity dashboard shows live send and receive speed and lifetime totals, with charts for throughput, total data, and items moved that you can hover, zoom, and pan; filter by device or date, browse about a month of history, and search a log that names every file. Optional clipboard sharing drops whatever you copy on one device into the other's Junk Yard — text, images, files and folders — where it waits as a scrap for you to copy when you want it, rather than landing on your clipboard by surprise; passwords are never shared. Two clear master switches in the Junk Yard header — Capturing and Sharing — let you stop saving copies, or stop sending them to every device, in one click.

Collab Sync · Two Macs

Keep a folder in sync with your other Mac

Got two Macs running Storage Studio? Collab Sync keeps one folder mirrored on both — home and office, or between two collaborators — with a real local copy on each Mac and no cloud in between. Save a file and it's on the other Mac within seconds; when both changed the same file, both versions are kept and you can restore either one.

Two-way folder mirroring is Mac-to-Mac; to bring a Windows PC into the mix, use Bridge to share and transfer files between the two. Pick a folder here and a direction — one way or both. Your request goes to the other Mac, where its owner chooses where to keep it and grants access, so a folder is never created without their say-so. Before anything starts you see exactly what will mirror: size, file count, and skipped hidden/cache items; your whole disk or Home folder can't be chosen. When both Macs edit the same file, the newer version is kept, the other is preserved and one-click restorable, and you're notified. If the other Mac has a file open you see a friendly "in use by…" hint. While the other Mac is away nothing piles up — the moment it's reachable, on Wi-Fi or across the internet, they do one catch-up pass. It all rides the same direct, end-to-end-encrypted link — your files never touch a server.

Junk Yard

A tidy home for everything you copy — that clears itself

Junk Yard quietly catches everything you copy — text, links, images, even files — onto a board of cards, alongside quick notes you jot down. Each scrap clears itself on a timer you choose, so your scratchpad never turns into clutter.

Pin what you reach for to the top; everything else tidies itself away on a timer from five minutes up to six months. Search the board by words — or, with Apple Intelligence on your Mac, by meaning and even the text inside an image — and filter by kind, by when you copied it, or by a colour you give each card. Copy several files at once and they arrive as one card. Flick your pointer to the screen edge for a slide-out curtain of recent scraps, or write a rich note with images you can resize and crop right in the app. Click any scrap to copy it back, ready to paste. Passwords are never captured, and everything stays on your Mac — no account, no network, nothing syncs. Paired with Bridge, a copy on one device can arrive here on the other.

IV · Safe & reversible by design

Move, never blindly delete. Every action is previewed and undoable, relocations leave working links, and Storage Studio keeps its own safety net.

Transfer & Backup

Move to a bigger drive — or keep a spare copy — safely

Transfer Drive copies everything to a new external drive, verifies it, then switches over — re-pointing every relocated app and folder so nothing breaks. Backup Drive makes the same verified copy and leaves your current drive active. Your old drive is never modified or deleted.

Both check the destination first — external connection, APFS/HFS+, enough free space, and a quick speed test — and ask for confirmation if a drive is slow or only usable with cautions (an internal or too-small drive can't be chosen at all). A live sheet shows percentage, speed, time remaining, and the file being copied. The copy runs in the background, so it keeps going if you close the app and resumes automatically if a drive is briefly unplugged. Before a transfer switches over, Storage Studio inspects the copy for completeness and asks once for your administrator password only if it needs to update protected app links.

Recycle Vault

Nothing is deleted — everything is recoverable for 6 months

Everything Storage Studio removes — a duplicate it clears, space it frees, an app you uninstall — goes to the Recycle Vault instead of being deleted, so you can always bring it back. With your external drive connected it rests there, versioned and recoverable for about 6 months, then clears itself. It's your own recoverable trash, separate from the Mac's Trash.

A dedicated window lists everything recoverable, newest first, with names, sizes, dates and how each was removed. Restore any file or folder to where it came from (never overwriting what's there) or to a new spot, restore several at once, or undo an entire removal in one step. Removals rest on your external SSD so the space genuinely leaves your Mac; if the drive is away, they're held safely on your Mac in the meantime and moved onto the drive automatically the moment you reconnect it — and a size limit means they can never fill your internal disk (if it's reached with no drive, new removals pause rather than risk it, so nothing is ever lost). You choose the holding-area limit, how many versions of each file to keep, and how much of your drive the vault may use. Tuhi knows what's in it, too — ask her "what's in my trash?" and she'll tell you, or restore it for you.

Restore Points

A safety net for Storage Studio's own memory

Storage Studio keeps a registry of everything it moved, so it never forgets where your files came from. Restore points protect that registry — and its settings — and put it back if anything ever goes wrong.

Your files are never copied into a restore point — only Storage Studio's own records and settings. One taken automatically before each batch of moves (make your own any time too). Change your mind? Roll Back Last Batch returns your most recent batch of moved files to where they came from, and never overwrites your data — if it can't return something safely it skips it and tells you. Records, not copies, so it costs almost no space; it lives on your external drive, tidies itself up, and repairs itself.

Data Backup

Versioned backups of the folders that matter

Back up the folders you choose to another drive or the cloud, and restore any earlier version any time — even if the original was deleted long ago.

It runs itself: automatic, incremental so only what changed is saved, and it picks up where it left off if a backup is interrupted. Cloud backups are encrypted on your Mac before they ever upload, so your files stay private by design. Works with your connected cloud accounts or any drive you have.

AI access (MCP)

Connect your AI assistant, privately

Let Claude and other MCP tools read your Mac's storage — free space, what's using it, your backups and transfers — so you get accurate answers grounded in your own machine.

Read-only and on your Mac only: everything stays on your Mac, so nothing leaves your machine. It's off until you switch it on, and you control access with a key you can revoke any time.
