xnview backup files remove utility (Python recipe) by Denis Barmenkov
ActiveState Code (http://code.activestate.com/recipes/577281/)

Currently XnView image viewer (versions up to 1.97.6) correctly rotate images only when option "[x] make backup" set.

Backup files have added name part '.xnbak' before extension:

original file: IMG0001.jpg
backup file: IMG0001.xnbak.jpg

Attached script take a root directory in command line and remove backup files created by XnView only when rotated file present in same directory.
