Brian, Oh that compression will help, thanks. However, once I have the image file I actually want to uncompress it and resize it so its down to the 10G. I will be using this file as a virtual image. I dont want it setting there taking up 100G when all it really is for me is 10G. How do I CHOP off the unneeded 90G. Jerry
