In the “Files” tab you can manage your personal files and share folders with other users. The files module is integrated in most other modules as well. So you can add files to Contacts, Projects, Tasks, Appointments etc.

The files module supports:

Share folders

It’s easy to share folders in Group-Office. Any user can do it. If you want to create a shared folder for the whole organization it’s recommended to do this as the “admin” user. Take the following steps:

  1. Right click on the folder that you want to share and click ‘Properties’

    Share folder 1
  2. Check ‘Activate sharing’

    Share folder 2
  3. Add the right user groups in the ‘Permissions’ tab.

    Share folder 3

The folder will show up under shared for other users. Not for the user that shared it.

Share folder 4


Visibility of files is solely dependent on the permissions defined for its containing folder. There is no way to hide individual files except to move them in a private folder.

Opening files

Opening files is as easy as a double click on the file of course. But you can also change the default action. For example you might want to edit text documents with Only Office, Microsoft Office Online or your own desktop application. You can view images in the online viewer or in a browser tab. To change this right click on a file and choose “Open with…”. Check the box “Remember my decision for this file type” to make it the default. Then choose your preferred action.

The Group-Office Assistant is a small program that you can install on your Windows, MacOS or Linux computer. It will automatically download files opened from Group-Office and monitor it for changes. When the file is saved it automatically uploads it back to Group-Office.

It also assists in mounting a network drive.
