Tom has a computer running XP and he's having issues with the accuracy of the number of files in his folders. Leo says that it sounds like the file index is corrupted. He can rebuild the index in the control panel. Windows XP's copy utility is broken also, so Microsoft's answer to that was to offer a separate file copier called "Robocopy." He could also try refreshing the folder in the folder menu. Otherwise it's probably time to upgrade to Windows 7. He should make sure to backup his data too.
