Windows 7, Revit and corrupt files

Since I installed Windows 7 last summer I've had growing problems with corrupt Revit files. These files cannot be renamed, moved or deleted, and hence the problem grows when the amount of these increases. I've tried 5 or 6 different programs for deleting corrupt files but only yesterday found one that worked for me: the latest version of EMCO's MoveOnBoot. It's free and you can find it here.
