Simple Python script that separates gifs from other image types. The script deletes itself on completion.

separateGifs.py

import os

count = 0

for filename in os.listdir('.'):
	if filename == 'separateGifs.py':
		continue
	elif os.path.isdir(filename):
		continue

	if filename[-3:] == 'gif': # If it's a gif, stash in gifs folder
		count += 1

		if not os.path.exists('gifs'):
			os.makedirs('gifs')
		
		print("Moving " + filename)
		os.rename(filename, './gifs/' + filename)

if count == 0:
	print("No gifs to move!")
else:
	print("Done!")
	os.remove('separateGifs.py')
