On the left side of the Management Center window there is a tree of groups and users. It has several filtering options which are useful in the later use of the application.
Above the tree, below the application logo the Show users field is located. The following options are described on it - All, Active session, With active backup.
- The All option displays all accounts available on the device, divided into groups created by the administrator. In each group an unrestricted number of accounts can be assigned, however, they will be visible only when you click on a particular group and expand it,
- With an Active session informs us which accounts are currently logged into the application on particular computers,
- The With active backup option indicates which of the accounts is currently sending backup.
The accounts in the system may also be searched by using the login. Just enter the login in the text field and click the Find user button.
Using the options listed above the user three, on the left 
you can enable or disable the filtering of some of its components. These are, from the left: Group, Users, Show disabled groups and users. This option allows you to disable the view on unnecessary for us elements of the tree in order to obtain a better overview of the application
While in the tree, by clicking the right mouse button on the name of one of the users, you can use the following options - Delete User, Disable user, Change group, Modify. The last option allows you to change your user account password and reset the encryption key.
Resetting the user encryption key causes an irretrievable loss of all files that have been sent by him to the Xopero server.
