Actually I wanted for tow reasons. I'll make my files cab like XP CD files. For example image.jpg to image.jp_. It'll save my disc space. If I use $OEM$ folder every body finds the files what I added extra in my CD. But in my desire method, no body will find my file in normal mode. On the other hand, I'm trying this step now. But it does not copy $OEM$files and folder. So I need eliminate $OEM$ folder.
