Run this code on Windows XP , it says "the file is being used by
another process" and fails to delete the file. I tried replacing :
#
for elem in filelist:
open( elem, 'w').write("Sel am")
#
with :
#
for elem in filelist:
fp = open( elem, 'w')
fp.write("Selam ")
fp.close()

Do you have any idea why my files cannot be deleted from my disk with
2nd part of my code ?

Why are you executing another program just to delete a file?

>>import os
>>os.remove('so me/file.txt')
