GWDG ownCloud

The service

With GWDG ownCloud you can upload your files to a server with a browser or client software, share them with other users or have them downloaded to one of your other devices by a client software.

GWDG ownCloud manages your files in so called “Folders”. A folder is basically the same as a folder or directory on your hard drive. All settings and actions on a folder always affect all of its contents as well. Folders can be created, shared, downloaded or deleted.

To use the service with a browser go to and log in with your email address and password. See “Who can use the service? How do I log in?” for more information about eligible accounts and registering accounts.

To transfer large files or a large number of files it is recommended to use the client software. Additionally the client can watch your files for changes and upload them to the service in the background or receive changes. This way your files are always up-to-date on the service and your connected devices running the client.

To access your files and folders via WebDAV refer to the guide by the manufacturer.
