How do I move a finshed game in to the archive folder to save it?
Thanks

There's a column called action and in that is a folder icon with a black arrowhead superimposed. Click it.

Tell me where the "column" is located on this site. Thanks

Click 'My Games'. You have a list of your games right? But including the finished game. Now read across. You should see the action column with the folder next to the finished game.

If not, then I've misunderstood your question.
