Just by defining a couple user-tags and doing some string processing on them (I could figure out the basics of PERL this much) I can now throw away my batch and shell scripts on Windows, do not need to go through the directories by "find", just do a recursive call to exiftool and that's it. I am getting an INCREDIBLE speed-up. NIIIICCCCEEEE! Folks, you should try this.

Thanks, Phil, much appreciated, Mixx
