Hello max & NG, >I don't quite understand what your program is doing. The user=a[18::20] >looks really fragile/specific to a directory to me.
I corrected it to user=a[18::5][:-2], it was my mistake. However, that command is NOT specific to a particular directory. You can try to whatever directory or net resource mounted on your system. It works. >>> a=os.popen("dir /s /q /-c /a-d " + root).read().splitlines() Mhm... have you tried this command on a BIG directory? On your C: drive for example? I had to kill Python after having issued that command because it ate up all my CPU (1GB) for a quite long time. There simply are too many files/information to retrieve in a single command. In my first mail, I said I have to work with a BIG directory (more than 1 TB) and I need to retrieve information when they become available (I put this info on a wxPython ListCtrl). This is why I have chosen os.walk() and that command (that runs on a separate thread wrt the ListCtrl). It does NOT run faster than your command (probably my solution is slower), but I can get information on every directory I scan, while with your command I have to wait a long time to process the results, plus the user can not interact with the results already found. >To get a list containing files owned by a specific user, do something like: >>> files=[line.split()[-1] for line in a if owner in line] I will try this solution also. Thanks NG for your useful suggestions. Andrea. -- http://mail.python.org/mailman/listinfo/python-list
