i to have the same problem cannot delete games not wanted if i find out will let you know.
chessmaster 11 question

I don't think you can erase an adjourned game from within CM11. You have to go to the folder it is stored in and manually erase it. BTW, I don't think you can erase a completed game at all. I would be pleased if someone can tell me otherwise :)

I was just experimenting and the only way I found that works is to go to the chessmaster program file on your computer, select Data, select Users, select the name you have the game saved under, select the game to be deleted, and delete.
In other words, I don't think it can be done through the program itself, but it can be done by finding where the game is stored on your computer's hard drive.
edit: looks like redlite-462 beat me to the answer by a minute!
I hate to bother anyone with this as I feel I should be able to find this either in the manual or in my intuition. But I can't.
I have saved a lot of games that I did not finish. I know how to load them back so I can finish them. But how do I delete those that I don't want to finish?
Thanks
