Mac storage questions, answered.

Storage Studio is a storage-management platform for the Mac. It unifies your internal drive, external drives, cloud accounts, and other devices into one intelligent space that's bigger than any single disk: it tiers big apps and folders to a fast external drive (leaving a shortcut so they still open normally), lets you browse both drives as one, and moves files across cloud providers. It includes Tuhi, a private on-device assistant powered by Apple Intelligence, and a multi-device ecosystem — Bridge sends files and clipboard directly between your own devices, and Collab Sync mirrors a shared folder between two Macs. Reclaiming space by moving instead of deleting is one capability among many, and everything is reversible. It lives in your menu bar and works on macOS 13 and later.

If you want space back without losing files, the best approach is "move, don't delete." Storage Studio relocates big apps and folders to an external drive (with a shortcut left in place so they still open), reclaims space macOS is holding in old snapshots, and keeps cloud files online-only — all previewed first and reversible. But it's more than a space cleaner: it's a storage-management platform that unifies your Mac, external drives, cloud, and other devices into one space, with an on-device assistant (Tuhi) and device-to-device sharing built in. Cleaners delete; Storage Studio moves, unifies, and connects. Try it free for 7 days.

If your goal is more free space without losing files, yes — Storage Studio does everything you'd reach a cleaner for, and reclaims space by moving instead of deleting. But it isn't really a cleaner; it's a storage-management platform. A cleaner deletes to make room. Storage Studio moves large apps and folders to a fast external drive (leaving a shortcut so they keep working), unifies your Mac, drives, and cloud into one space, and connects across your devices with Bridge (device-to-device transfer and clipboard) and Collab Sync (shared folders between two Macs) — all preview-first and reversible. It also includes Tuhi, a private on-device assistant powered by Apple Intelligence.

Yes. Storage Studio asks before it deletes or overwrites anything, previews every move before a byte is touched, and leaves a shortcut when it relocates a file so nothing disappears from your folders. Everything is reversible, and the app is notarised by Apple.

Storage Studio runs on Macs with Apple silicon (M1 or later) and supports macOS 13 Ventura through the latest releases (Sonoma, Sequoia, Tahoe). Intel Macs aren't supported by new versions — if you have one, you can keep using version 4.17.1, the last version for Intel, and it won't offer you updates it can't run.

Empty the Trash, clear app caches, remove old downloads, and move large apps and folders you rarely use to an external drive. Storage Studio does all of this in one tap with Tuhi — it clears caches and rarely-used files, reclaims old local backups, and keeps cloud files online-only, previewed first and fully reversible — so you get gigabytes back without hunting through Finder.

Pair your Mac with an external SSD and offload what you don't need on the startup disk. Storage Studio moves large apps, folders, and media to the external drive and leaves a shortcut in the original spot, so you reclaim space while keeping every file — nothing is deleted.

Yes — app caches rebuild automatically, so clearing them safely reclaims space; the only risk is deleting the wrong thing by hand. Storage Studio clears only known-safe caches and rarely-used files, shows a preview first, and never touches your personal files without asking.

Keep at least 10–15% of your drive free so macOS has room for virtual memory, updates, and temporary files — performance drops when it's nearly full. Storage Studio watches your free space and helps you keep it in a healthy range automatically.

That warning means your boot drive is nearly out of room. Clear caches, delete large unused files, and relocate big apps and folders to an external drive. Storage Studio fixes it fast: it moves the biggest items to a fast external drive and leaves a shortcut behind, so your startup disk has room again while everything still opens normally.

"System Data" is the catch-all bucket — caches, logs, local snapshots, and app support files — and it can grow to tens of gigabytes. You can't delete it directly, but you can shrink it. Storage Studio's What's Using Space pinpoints the biggest contributors and clears or relocates them safely, so System Data comes back down.

macOS often keeps the freed blocks in APFS local snapshots (local Time Machine copies) until they age out, so deleting files doesn't show as free space right away. Storage Studio surfaces those snapshots and reclaims the space with one click — and after a big move it auto-thins them so the space appears immediately.

Dragging an app to another drive can break it, because macOS expects it in /Applications. Storage Studio relocates the app to your external drive and leaves a shortcut in place, so it still launches normally from Launchpad, Spotlight, and the Dock — and you can move it back in one click.

Plug in a USB-C or Thunderbolt SSD and let Storage Studio pair it with your internal drive as one workspace. It moves big folders, libraries, and apps to the SSD with a shortcut left behind, so your MacBook behaves like it has a much bigger disk — fast enough to work directly off the external drive.

Yes — large Photos, Final Cut, and iMovie libraries are common space hogs. Storage Studio relocates them to an external drive while keeping them usable, leaving a shortcut so your apps still find them, and it preserves dates and metadata on the move.

Not the way Storage Studio does it. It leaves a shortcut (symlink) at the original location, so apps, Finder, and Spotlight resolve everything as if it never moved — and the move is fully reversible.

Online-only files live in the cloud and download on demand, freeing local space. Storage Studio can keep iCloud Drive, Dropbox, Google Drive, and OneDrive files online-only as part of Tuhi, so downloaded copies stop piling up on your Mac.

Yes. Storage Studio's Data Transfers connect Google Drive, Google Photos, Dropbox, OneDrive, Box, and any S3-compatible service (AWS, Cloudflare R2, Backblaze B2, Wasabi, DigitalOcean Spaces, MinIO), plus FTP and SFTP — and it can move, copy, or sync between any of them in either direction.

Yes — that's My Drive, and it comes with every Storage Studio trial and licence, with nothing else to buy. Open the Delta Drive tab, choose Use storage you own, confirm your email with an 8-digit code, and connect an Amazon S3, Cloudflare R2, Wasabi, DigitalOcean Spaces or other S3-compatible bucket. Your files stay in your own storage, appear in Finder like a disk, and open in any browser at storagestudio.us/drive. Storage Studio only works inside one folder of the bucket you name, and switching between drives copies nothing and loses nothing.

Yes. From My Drive you can share a file or folder with named people, set an expiry, and choose whether they can read, comment or edit — you can withdraw it any time and see who opened it. Each share belongs to the drive it was made on, so if that drive is switched off the people you shared with are told it isn't available right now, never shown anything else.

My Drive is paused, not removed, and nothing in your storage is touched — your files stay in your own bucket. While paused it can't be opened on the web and anything you shared is paused; on your Mac you can only disconnect or remove it. Reactivating Storage Studio picks up where you left off. If it stays paused for six months, the storage keys you gave us are forgotten (you're emailed two weeks before); your files never are.

Purgeable space is storage macOS is holding — old snapshots, cached cloud files, optimised media — that it frees automatically when you need room, which is why "free" space can look smaller than expected. Storage Studio reclaims a lot of it on demand instead of making you wait.

macOS keeps point-in-time APFS local snapshots so Time Machine can restore even when your backup drive is away — useful, but they can hold a lot of space. Storage Studio lists every snapshot, shows which are already safely backed up, and reclaims the space you choose in one click.

Not unless you ask it to. Freeing space, moving apps and folders, and reclaiming snapshots all happen on your Mac and your external drive. Your files only leave your Mac when you choose to — syncing to a cloud account you connected, backing up to the cloud, or using My Drive on storage you own — and then they go to the storage you picked. Otherwise only licence validation and optional telemetry touch the network.

Yes — Storage Studio includes Tuhi, an assistant powered by Apple Intelligence that answers your storage questions and can even tell you why your Mac feels slow, hot, or low on memory. It runs entirely on your Mac, works offline, and never exposes file paths or anything private.

Nothing — your files stay exactly where they are on both drives. Storage Studio simply stops moving new things; it never holds files hostage or makes you re-import anything to keep using them.
