Question

I’d like to check the archive bit for each file in a directory using python. So far i’ve got the following but i can’t get it to work properly. The idea of the script is to be able to see all the files that have the archive bit on.

Thanks

# -*- coding: latin-1 -*- import os , win32file, win32con from time import * start = clock()  ext = [ '.txt' , '.doc' ]  def fileattributeisset(filename, fileattr):     return bool(win32file.GetFileAttributes(filename) & fileattr)  for root, dirs, files in os.walk('d:\\Pruebas'):     print ('root', root)         print ('dirs', dirs)     print ('files', files)     for i in files:         if i[ - 4:] in ext:              print('...', root, '\\', i, end=' ')             fattrs = win32file.GetFileAttributes(i)             if fattrs & win32con.FILE_ATTRIBUTE_ARCHIVE:                 print('A isSet',fattrs)         #print( fileattributeisset(i, win32con.FILE_ATTRIBUTE_ARCHIVE))      print ('####') 

EDIT: all files appear to have the archive bit on, doing ‘attrib’ shows that all files have no attribute bits on.

Answer 1

The file list returned from os.walk are not fully qualified paths, so when you call

win32file.GetFileAttributes(i) 

it can’t find the file and returns an error code; which happens to be -1. So the operation

fattrs & win32con.FILE_ATTRIBUTE_ARCHIVE  

is always true.

You need to join the root to the filename so that GetFileAttributes will succeed:

fattrs = win32file.GetFileAttributes(os.path.join(root, i)) 

Also, when you are checking the extension, it is probably better to use os.path.splitext(path) to retrieve the extension rather than relying on them be 3 characters long as you do.
