Moving played game to archive status

I have 480 completed games that I would like to move to archive status. Is there any way I can move several games at one time to archive status or do I have to move them one by one?

If you are using a computer, go to 'my games'.
on the top right of the page, select 'manage games'.
on the new page look on the top left, and click 'select all'.
then go through the games and unselect those that you do not want to move.
click 'move' on the top left, and then select the folder to move them to.

Let us know if that helped!
