I just finished creating my XP ISO with nlite, I must have done something wrong the total ISO size is 360MB, whereas the original OS files were 354MB and on top of that I slipstreamed a number of programs, kaspersky, office 2003, power dvd etc. I must have missed something out or made a mistake with the addons. I added all my programs along with the ryanvm post SP2 update pack on the select hotfix screen and it all seemed ok, but now with this weird final file size im confused. Im wondering do I still have to include the CAB files of each program that I wanted to add on the CD in a seperate folder, this would exlain the small file size as nlite would only have to specify where the external CAB file is and not actualy include the whole file in the final image. sorry for the long winded explenation, I understand if its confusing thnx in advance Goldpenny
