yes friends, I read all of them. I delete WIN9XMIG,WIN9XUPG folder.but not WINNTUPG for using windows recovery console.. Also I delete LANG folder..default it's 99 mb but now 2,53 mb..I delete components,docs,valueadd,support folders.. but I make a cd that I integrate a lot of programs with RVM integrator(554 mb) and after I add driverpacks all drivers It became 786 mb..It includes; * DriverPack Chipset * DriverPack CPU * DriverPack Graphics A * DriverPack Graphics B * DriverPack Graphics C * DriverPack LAN * DriverPack MassStorage * DriverPack Sound A * DriverPack Sound B * DriverPack WLAN so it will 786 mb..maybe it not contains DriverPack WLAN..but it's not enough for me. added: I want to learn is it safe to overburn windows-cd?
