If you really think about it, you will find that you are using it
incorrectly. You invoke calls like

os.path.isdir("console.log")
os.path.isdir("RECYCLER")

Now, these are all relative paths. What *parent directory* should
Python assume? You are assuming r'f:\\', but how could Python possibly
know about this assumption?
