Python: script to clean windows disk after % usage

Question

I created a python script for cleaning old files on a windows disk. Now I want to improve that script and check if I went over a predefined disk usage and then delete files ... how I can do it? Here's my code:

import os, time

path = r"f:\backup"
now = time.time()
for f in os.listdir(path):
    if os.stat(f).st_mtime < now - 180 * 86400:
        if os.path.isfile(f):
            os.remove(os.path.join(path, f))

I need it because I've configured a backup of my computer on external disk and sometimes it can't do the backup because disk is full.

What behavior are you looking for when disk space is exceeded? What will you remove in that case? — selllikesybok

BTW, it would likely be a little faster to reverse the order of your if tests. — martineau

I would recommend checking out this answer:

Cross-platform space remaining on volume using python

The nt implementation of the os module does not include the statvfs attribute, so you'd need to recreate that functionality using c_types.
