Source path: E:\VRMPVOL_EN Destination path: E:\packedxp It didn't do anything after clicking the "Pack these files to the destination" button. It just stayed idle as if nothing even happened. I had about 20 GB of free space left on my E drive. I am currently running xp sp2. I keep my computer really clean, so virsuse, spyware, etc is never a problem. I also rebooted and tried without running any other applications in the background and still the same thing happened. I can't think of any other info that may help you. But I'd be more than willing to give you specifics if necessary. Thanks!
