PathWatcher.py keeps an eye on any changes in any directory

This little script runs only on windows and watches at low level into a givven directory. If any changes occur, it will immidiatly show you what has changed. I use it regularly to watch into a directory (works also with UNC pathes and samba) and follow, which files were modified. It watches into the complete directory tree with sub directories. Very simple, use it like this:

python.exe c:\temp\PathWatcher.py \\SRVXY\released_docs

import os, sys

import win32file
import win32con

ACTIONS = {
  1 : "Created",
  2 : "Deleted",
  3 : "Updated",
  4 : "Renamed from something",
  5 : "Renamed to something"
}

FILE_LIST_DIRECTORY = 0x0001

path_to_watch = sys.argv[1]
print 'Watching changes in', path_to_watch
hDir = win32file.CreateFile (
  path_to_watch,
  FILE_LIST_DIRECTORY,
  win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE,
  None,
  win32con.OPEN_EXISTING,
  win32con.FILE_FLAG_BACKUP_SEMANTICS,
  None
)
while 1:

  results = win32file.ReadDirectoryChangesW (
    hDir,
    1024,
    True,
    win32con.FILE_NOTIFY_CHANGE_FILE_NAME |
     win32con.FILE_NOTIFY_CHANGE_DIR_NAME |
     win32con.FILE_NOTIFY_CHANGE_ATTRIBUTES |
     win32con.FILE_NOTIFY_CHANGE_SIZE |
     win32con.FILE_NOTIFY_CHANGE_LAST_WRITE |
     win32con.FILE_NOTIFY_CHANGE_SECURITY,
    None,
    None
  )
  for action, file in results:
    full_filename = os.path.join (path_to_watch, file)
    print full_filename, ACTIONS.get (action, "Unknown")
