Remove jpg when raw existing

remove_jpg_if_raw_exists.py

#!/usr/bin/env python
# Script:      remove_jpg_if_raw_exists.py
#
# Description: This script looks in all sub directories for
#              pairs of JPG and RAW files.
#              For each pair found the JPG is moved to a
#              waste basket directory.
#              Otherwise JPG is kept.

Thanks @tazztone. It was written when Python 2 was widely used. I will fix it when at home.

yea would be nice if upgraded to python3. idk how to code, i just asked chatgpt what might be wrong with the script.
changed line 24 to waste_dir = r"X:\2023\waste" so that it doesn't create a folder named "3" (coz apparently \202 is interpreted as "octal escape"?)
while running it i found that the waste-jpgs get moved beside "waste" folder, instead of inside it.
idk maybe this helps u to fix with less effort.
