I was just reviewing WinDirStat, the open source disk mapping software (shows you where big fat files are hogging up your disk, very cool) and it found a 2GB file and a 744MB file, called respectively PrlsCmps0.dat and PrlsCmps1.dat in my user directory at the top level. At first I was baffled, but then I read it phonetically and I realized it sounded a lot like Parallels Compressor. Any idea what these files are, and whether I can delete them? I haven't compressed this installation yet, been installed for a few months, perhaps it's begging me to do so and these are the files that get squished?
