Is it possible to delete archived games?

Is it possible to delete archived games? If so, how do I do it?

No, they are a permanent part of the site and cannot be deleted.
However you can manage where you store them.
If you go to your 'my games' page you can manage your games from there.
There are a few default folders that cannot be modified but you can create and name additional folders in which to store them.

Thanks for your help.
