You can copy your games easily with the Manager. To copy a game:
1. Click on the little boxes next to the games you want in the source or destination list.
2. From the Game menu, choose Copy and then choose From Dest to Source if you want to copy games from the Destination directory to the Source directory, or From Source to Dest if you want to copy from the Source directory to the Destination directory.
3. The games will be copied. This may take a little while depending on how many games you selected and the place they are being copied from (copying games from a slow network will take longer than copying games from a local hard disk).
