I'm trying to count files and dirs on a Win XP system... I'm trying to 
do so with a great degree of accuracy. Here's what I've tried:

def fs_object_count():
    file_count = 0
    dir_count = 0
    for root, dirs, files in os.walk(/):
       file_count += len(files)
       dir_count += len(dirs)
    print "Number of Files Examined: ", file_count
    print "Number of Folders Examined: ", dir_count
    print "Total number of FS Objects is:", file_count + dir_count

I've also tried this:

def fs_object_count():
    fs_list = []
    for root, dirs, files in os.walk('/'):
       for d in dirs:
          fs_list.append(d)
       for f in files:
          fs_list.append(f)
    print len(fs_list)

Both functions produce the same results (33,000 files)... the problem: 
the filesystem has twice as many files (66,000) than the actual sums of 
these two counts when doing a virus scan or an adaware scan. To make 
matters more confusing... the IBM Tivoli backup software that I use 
confirms the Python counts when it does a backup. I don't know of a way 
to see what the OS has to say what it thinks is correct. Any ideas on 
how to do this?
