Find files with extension .tdarrcache* on d:/. If the files are over two days old, delete them. Log the results to d:/tdarrremoved.txt.

import os
import time
import datetime


#create a log file with the time
logFileName = "d:/tdarrremoved.txt"
with open(logFileName, 'a') as f:
  f.write("{}".format(datetime.datetime.now()))
  f.write("\n")


d = "d:/"

for f in os.listdir(d): 
  if f.endswith(".tdarrcache"):
    fileTime = os.path.getmtime(d+f)
    twoDaysAgo = time.time() - (60 * 60 * 24 * 2)
    if fileTime < twoDaysAgo:
      os.remove(d+f)
      with open(logFileName, 'a') as f:
        f.write("{}".format(f))
        f.write("\n")
