There are four types of user permissions for folders in Media Center: Write: This means the user can change the folder name.
Manage: This permission allows users to move and delete artworks/files, and add users.
Share: Users with this permission can view and share files and artworks within the folder.
Download delivery files: Users with this permission can download delivery files.
If you added a user but did not select any of the permissions, the user can only view the contents of the folder.
