I use cdimagegui in windows vista64 to make unattended/sysprep 2k/xp CDs.

I am using the duplicate files option so that I can put the i386 folder twice in the cd, so I don't have to manually or script copy it to the windows folder.

After the installation, the i386 folder in %windir%, shows up as almost twice the size as it is on the CD. But the same amount of files and folders are listed.

Has anyone else seen this and if so how did you fix it?

I also tried the oscdimg 2.54 tool from the WAIK and I get the same result. For instance, the i386 folder on the customized unattended WinXP CD is 413 MB, but in the C:\windows folder the i386 folder is 783 MB.
