[Tbird]

I would like to know where both betmost and Hem store the handhistories, because I would like to delete some so they do not show up in my graph, but i dont know how to do that

Deleting cashgame hands or tournament hands?

If cashgame hands: options--> settings--> purge hands
Or manually delete the hands by right-click delete them in the sessions/hands/reports tab.
