You don't really give enough information, but I'll make some
reasonable guesses. My guess is that you have a directory tree
"E:\myDir1\MyDir2", and that "MyDir2" contains files but no

Here you are iterating over a directory tree. For each directory in
the tree, os.walk returns the path to the directory, a list of the
subdirectories in that directory, and a list of non-directory files in

Here you are examining each of the subdirectories of the current
directory. You are ignoring any files in that directory. So, for the
top-level directory you gave to os.walk, "E:\myDir1\MyDir2", you are
ignoring the actual files in that directory, and examining only its
subdirectories. My guess is that there are no subdirectories, so you
get no results.

Unsurprisingly. If there are any files in "myDir1", your code would
ignore them, and only find files in its subdirectory, "MyDir2".
