Configure VMWare to add external media to the guest (external USB stick, floppy image, SAMBA share if you can have it networked) and configure the guest to boot from a Live CD like KNOPPIX or Helix 2008R1
(no need to burn it, just the ISO should do). Don't mount the guest's partitions but just point testdisk to the partition containing the deleted files after reading some basic instructions
. Save the file to your external media.
