The service

With GWDG Cloud Share 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 Cloud Share 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.

Additional information

Firewalls, client connections, servers

The client connects to our servers on port 1337 and to the central address or at ports 80, 443, 1337. For Peer2Peer connections parallel to the synchronization to the server the client opens the port 1337 locally. Connections to and from this port are optional.

The service operates within the network of GWDG in the address range of and corresponding DNS names. If you operate a firewall locally it is recommended to allow connections to and from these addresses to enable normal utilization of the service. Otherwise usage of the service will be degraded and cannot be supported.
