Hmm, the file is a Red Hat Fedora DVD iso I dld & Win reports as: 4.25 gb, 4,572,612,608 bytes, 4,572,618,752 bytes used. Win doesn't lie does it I use "HashCalc" for my checksum checks. Maybe with all the changes to Win 98se[uSP2, 98se2ME, WUPG, + other little tweaks] , it just wierded out on me PS: Maybe 2 + 2 doesn't always = 4 .....? LOL!
