[Python] Deleting files by date from directory with a few million files

Recent problem: Single directory with 5.3 mio files. Using find did not work because it was filling memory up. I tried anything I can think of but in the end had to go with python to iterate over the directory. I used https://github.com/benhoyt/scandir 
Following Code will do the job

1 2 3 4 5 6 7 8 9 10 11 12 13

import scandir import time import os old = time.time() - 28 * 24 * 60 * 60 #28 days for entry in scandir.scandir('/tmp/test'): #print(os.path.getctime(os.path.join('/tmp/test',item))) try: if (os.path.getctime(os.path.join('/tmp/test',entry.name)) < old): os.unlink(os.path.join('/tmp/test',entry.name)) except: pass

This new scandir version is implemented since python 3.5. If you don't have it just download the scandir.py and put it in the same directory as this code.
