Python-implemented folder cleanup program sharing

Use:

The code is as follows:

foldercleanup.py-d 10-k c:\test\keepfile.txt C:\Test

Indicates that the C:\Test directory retains only the last 10 days of subfolders and subfolders specified in Keepfile.txt.

Code:

The code is as follows:

Import Os.path
Import datetime

Keep the last zip file in the directory:

The code is as follows:

def keeplastnumzips (num)
Def extracttime (f):
Return Os.path.getctime (f)

Zipfiles = [Os.path.join (Zipdir, F)
For f in Os.listdir (Zipdir)

If Len (zipfiles) > num:
Zipfiles.sort (Key=extracttime, Reverse=true)
For I in range (num, len (zipfiles)):
Os.remove (Zipfiles[i])
