Depending on the level of your ChessBase membership you can create a large number of databases, which you can later delete.

 

 

The databases "My Games", "Repertoire White" and "Repertoire Black" are pre-installed. If you try to delete these databases all the games in them are removed, but the databases themselves remain.

 

 

 

The status line below the database symbol gives you information about the account name and the amount of space that is used on the server.
