Delete certain files --- This very short python script simply deletes all files with a certain extension (or some other pattern). I took photos on a bike ride and the SD card was riddled with raw files and the JPG files; I only needed the JPG so this script removes any unwanted files.

delete_files.py

import glob
import os

filenames = glob.glob('*.ARW')

for file in filenames:
    os.remove(file)
    print(file + " has been deleted, moving on to next file")

print("All files have been deleted, thank you")
