Hi Jason,

os.path.isdir and .isfile needs the full file name of the file.

Try this:

import os;

sDirectory = "d:\data";

def process_directory(sArg, sDirName, lNames):
    print "\nProcessing directory %s (%d items)..." %
(sDirName,len(lNames));
    for sItem in lNames:
        fullFileName=os.path.join(sDirName, sItem)
        if (os.path.isdir(fullFileName)):
            print "    - Directory: %s" % sItem;
        elif (os.path.isfile(fullFileName)):
            print "    - File: %s." % sItem;
        else:
            print "    - Unrecognized: %s" % sItem;


os.path.walk(os.path.normpath(sDirectory), process_directory, "")


By the way, I recommend you use sDirectory = r"d:\data", that is, use a raw
string instead of a normal one, otherwise you get into trouble when you
change the file name to e.g. "d:\temp", as "\t" is a tab character.

Another thing is that you do not need to put ";" after each statement,
unless you want to.
