Have you not found out yet that windows likes to hide its little trinkets in various places?
You can usually find TIF's in at least three different folders.
I wrote a batch file in XP to remove all the junk files from all of XP's little hiding places. That batch file is nearly forty lines long.
Without such a program, you'll probably find MS's "Disk Cleanup" to be very helpful. Run it in Extended mode for an even better cleanup.
here's the shortcut to run Disk Cleanup in extended mode.
%SystemRoot%\System32\Cmd.exe /c Cleanmgr /sageset:35 & Cleanmgr /sagerun:35
Just copy and paste this shortcut into a NEW desktop shortcut and run it for a much improved cleanup of your HD.
When selecting items for the program to remove, its safe to select anything but "Setup Logs". leave those alone.
