Cannot delete numanuma.mp3:Cannot find specified file

I kept Norton Commader, a DOS program from Peter Norton (before Symantec bought him out), which lets me get rid of lots of things that windows xp refuses to delete and it works from within windows in ordinary or (if necessary) safe mode. It is called NC.exe. I kept it on a bootable floppy for checking out PCs at auctions and for helping other people with problem PCs. I put it on all my computers.
