Questions and answers

Storsum costs nothing to use today. The space comes from the free plans of your own accounts, so you can start with just a Google account and add more as you go.

In your own storage accounts: your Google Drive, Box, pCloud, Koofr or buckets. Storsum’s server streams each file to one of them and keeps only what it needs to find it again, such as its name, folder and which account holds it. File contents are never written to the server’s disk.

Not the ones you encrypt, which is every upload unless you choose otherwise. The provider gets a file named something like 3f2a….enc holding scrambled data; the real name stays with Storsum. Files you upload without encryption are stored as they are, so you can also open them in the provider’s own app.

New uploads go to an account that still has room. On the Storage page you can see how full each account is, move files from one account to another, or choose how uploads are spread: most room first, taking turns, or in an order you set.

No. You can sign up with an email and password and connect Box, pCloud, Koofr or any S3 bucket. Signing in with Google simply connects that Drive straight away.

Press Import from Drive on the Files page. Storsum then lists every file you own in your Drive, in folders like Drive’s, without copying or moving anything, and Sync keeps that list up to date. Renaming one in Storsum renames it in Drive, and deleting one for good from Storsum’s Trash deletes it from Drive too.

Yes, with a link: anyone who has it can open or download the file, and you can stop sharing at any time. Invites, which share a file or a whole folder with someone by email, need them to have a Storsum account.

On the Storage page, choose Move all files on that account to move its files to your other accounts, then Disconnect it.

Not yet. The website works in Safari on a Mac, an iPhone or an iPad, with the same drive and the same features.

The installer isn’t code-signed yet, so Windows shows “Windows protected your PC” the first time. Choose More info, then Run anyway.

Deleting moves it to Storsum’s Trash first, where you can restore it. It is removed from your provider only when you delete it for good from Trash.

Each provider’s own terms apply to your account, as they would with any app you connect. Storsum uses only the access you grant when you connect an account, and stores files there the way any app with that access would.
