Files
Your files, on a server you control.
A real file browser with previews, versions, sharing and resumable uploads. Files stay as plain files on disk, so you can always walk away with them.


Upload anything
Drag whole folders in. Uploads resume after a dropped connection, with pause and retry.
Versions
Overwrite a file and the old content is kept, thinned over time.
Share on your terms
Share with people and groups, or make a public link with an expiry, a password or upload-only file drop.
Sync to your computer
The sync client keeps a folder on your machine in step with your Home.
