By default, Python has a recursion limit of 1000 deep; that is, your
function is calling itself 1000 times without returning.

In this case, the only reason why you hit the recursion limit is if you
have a directory which is 1000 deep (quite unlikely, Windows has a
directory depth limit much lower than that).

Or your function somehow never returns, in a typical recursive function,
it's usually because you have problem in the precondition.
