Delete files named *.tdarrcache* on D:\ only if they are over 2 days old.

import os

# Delete cache after 2 days
cutoff = now - (2 * 86400)

for root, dirs, files in os.walk('D:\\'):
    for name in files:

        st = os.stat(filename)
        if st.st_mtime < cutoff and name.endswith('.tdarrcache'):
            os.remove(filename)
