XPM without raw files

as stated in my other article, I am used to work with xmp-files when working with lightroom.
For the reasons, why, read the corresponding article on

when deleting an image via lightroom, the xmp files goes away as well. but I also use faststone viewer to quickly select/delete images. This tool does not show the raw file, nor takes into account the LR changes out of the XMP (it uses the embedded jpg-format), but it is much faster than LR, and thus much faster do just delete the 'garbage'.
when doing this before importing into LR, no problem, there are no XMP's yet, but sometimes I use it after already having done things in LR, and then the XMP remains there.

I looked on the internet (where 'everyting' can be found), and found a BAT-file for doing the cleanup of these orphan xmp's. but I changed the bat-file to make it more user friendly.

you can put this file in any location and run it from there, it will prompt for a directory to treath

the subroutines are embedded, thus there is only one bat-file

you can do a simulation-run, doing everything but the delete

the code.
copy the text, and save it somewhere as a .bat, e.g. cleanuporphans.bat
