Open a 50 GB project straight from the cloud.

TurnDisk is a cloud drive for Mac, made for big files. It sits in Finder like an external disk, fetches only the parts of a file you’re using, and never fills your Mac’s own disk.

An illustration of TurnDisk at work. A 48.6 GB video plays while only the part being watched is fetched; jumping ahead fetches only the new spot; saving an edit to a 9.8 GB audio file uploads one small piece; and a 3.2 TB library keeps only 4.6 GB on the Mac.

For people whose files are bigger than their Mac.

If your work comes in tens or hundreds of gigabytes, you’ve met the full-disk warning. TurnDisk keeps all of it one click away in Finder, without keeping it on your Mac.

Video editors

Cut from footage on the drive. Your editing app reads the frames it needs, and TurnDisk fetches them as you play and scrub.

Photographers

Keep every shoot on one drive without buying a bigger Mac. Open any raw file from any year when a client asks for it.

Sessions, stems and bounces live in the cloud. The files you open come down as your app reads them and stay ready while you work.

A 256 GB MacBook Air can still have your whole archive in Finder. It just doesn’t have to hold it.

What makes it different from a sync folder.

Most cloud storage copies files onto your Mac before an app can use them. TurnDisk reads them straight from the cloud, a piece at a time.

Big files play while they arrive

Open a 40 GB video and it starts without a 40 GB download first. TurnDisk fetches the part being played, plus a little ahead, and jumps straight to wherever you skip to.

It’s a disk, not a folder to keep in sync

TurnDisk mounts in Finder like an external drive. There’s nothing to choose to download and nothing to babysit. Every app sees ordinary files, because to the app it’s just a disk.

Listed under Locations, next to your Mac’s own disk, with an eject button.

Your Mac’s disk stays free

TurnDisk keeps at most 5 GB of your files on your Mac, and you can change the limit. When it’s full, the files you haven’t opened for longest make room. They’re still on the drive, and come back when you open them.

Editing a big file doesn’t re-upload it

Change part of a big file and only the pieces that changed are sent, often a few megabytes. Uploads run in the background while you carry on, and pick up where they stopped if the connection drops.

A fix to a 9.8 GB audio file: only the changed piece goes up, a few megabytes.

The safety net you’d expect.

Mistakes happen, computers crash, two Macs edit the same file. Nothing here is unusual, and none of it is missing.

  1. Bothversions kept

    Two computers, one file? You keep both.

    If the same file is changed on two computers at once, TurnDisk keeps both side by side, so nobody’s work is overwritten.

  2. 30 daysin the Trash

    Deleted files wait in the Trash

    Deleted something by mistake? It stays in TurnDisk’s Trash for 30 days, ready to restore.

  3. 30 daysof versions

    Go back to an earlier version

    Saved over something you needed? Earlier versions of a file can be restored for 30 days.

  4. Keptthrough crashes

    Crashes and power cuts don’t lose your work

    Changes are held safely on your Mac until they’ve been uploaded, and are never cleared out to make room.

What TurnDisk doesn’t do yet.

Better to read it here than find out after you’ve moved 2 TB.

No sharing

You can’t share folders or send links yet. TurnDisk is for one person’s files on their own computers, not for a team.

Mac only, for now

Windows and Linux are planned. There’s no phone app, and no way to browse your files in a web browser.

Not end-to-end encrypted

Files are stored with Cloudflare, which encrypts them at rest, as most cloud storage does. TurnDisk staff never see what’s inside your files.

You need a connection for files you haven’t opened

Files you’ve opened recently, and folders you mark to keep offline, work without internet. Everything else is fetched when you open it.

Three steps to a drive in the cloud.

  1. Create your account

    Sign in on this website with Google or Apple. Your account starts on the Free plan with 1 GB.

  2. Install TurnDisk on your Mac Coming soon

    The Mac app isn’t available to download yet. When it is, sign in with the same Google or Apple account.

  3. Move your big files onto it

    TurnDisk appears in Finder like a disk. Drag your footage, photo library or sessions onto it, then delete the copies on your Mac once they’ve uploaded.

Download TurnDisk.

Install the app, sign in with the Google or Apple account you use here, and TurnDisk shows up as a drive on your computer.

One account and one plan cover every computer you sign in on.

Your account, your files, your call.

No new password to remember

Leave whenever you like

Export a copy of everything, or delete your account, at any time.

Pick how much space you need.

Every plan has every feature, on all your Macs. They differ only in space. Start free to see how it fits into your day, then upgrade when you move your library.

Questions people ask

Do I have to download a file before I can open it?

No. TurnDisk fetches the parts of a file an app reads, as it reads them, plus a little ahead. A video starts playing straight away and the rest arrives as you watch. Skip to the middle and TurnDisk fetches the middle, not everything before it.

Will TurnDisk fill up my Mac’s disk?

No. By default TurnDisk keeps at most 5 GB of your files on your Mac, and you can change that limit. When it’s full, the files you haven’t opened for longest make room. They stay on the drive and come back when you open them.

Changes that haven’t uploaded yet are never cleared out. Folders you mark to keep offline are kept on your Mac in full.

How is this different from a sync folder?

A sync folder copies files to your Mac and keeps the copies in step with the cloud. Apps usually wait for a whole file to download before they can use it. TurnDisk is a disk: apps read files from it directly, and only the parts they read come down. A 3 TB library doesn’t need 3 TB, or even 300 GB, on your Mac.

Can I download the Mac app now?

Not yet. The Mac app is coming soon. You can create your account now, and it’ll be ready to sign in to when the app arrives.

Can I share files or folders with other people?

Not yet. There are no shared folders or links, so TurnDisk is for your own files on your own computers.

Does it work on Windows, Linux or my phone?

Not yet. TurnDisk is for the Mac first, and Windows and Linux versions are planned. There’s no phone app and no web file browser.

How big can a single file be?

Up to 1 TB per file, as long as it fits in your plan’s space.

What happens when I’m offline?

Files you’ve opened recently keep working, and so do folders you’ve chosen to keep offline. Changes you make are saved on your Mac and upload by themselves when you’re back online.

What if the same file is changed on two computers?

TurnDisk keeps both versions side by side, so neither change is lost. You decide which to keep.

I deleted or overwrote something. Can I get it back?

Yes, for 30 days. Deleted files go to TurnDisk’s Trash and can be restored for 30 days. Earlier versions of a file can also be restored for 30 days.

Can TurnDisk see my files?

TurnDisk staff never see what’s inside your files. Your files are stored with Cloudflare, which encrypts them at rest.

To be clear about what that means: this is not end-to-end encryption. To help with support, TurnDisk can see account details, how much space you use, and the names and sizes of files and folders. The privacy policy has the details.

Does one plan cover all my computers?

Yes. A plan belongs to your TurnDisk account, so it applies on every computer you sign in to with that account.

How do I cancel?

Sign in on the account page and choose Cancel subscription. Your plan stays until the end of the period you’ve paid for, then your account goes back to Free. Your files are never deleted. See the cancellation and refund policy.

Stop deleting files to make room.
