GottaBeMobile Forum Moderator Sharon Treloar, aka sbtablet, shared a clean-up tool that is built in to the SP1 upgrade a few days ago. It essentially deletes all of the pre-SP1 files if you are sure you won’t be reverting back. In the process, it cleans out anywhere from 800MB to 1.5GB of space. Rob Bushway, forum member segalsegal, and myself all ran the disk cleanup tool and regained approximately 800MB of disk space. I couldn’t believe how easy it was! Thanks Sharon!
