Thats great, but what if instead of reading every sub-directory at once, the user can insert a depth limit?

-1 = everything 0 = only the main level 1 = only the main level and its sub-directories 2 = (...)

The implementation is not recursive, it should only read the contents of the directory, not sub directories. A recursive read can be done through a loop.
