Yes, I want to write a module which gets as parameter the path to a directory.
In the module I want to be able to find all files and subfolders in that directory.

Mh, I don't really have a clue. What are the differences?
I'm not interested in all the inode information or some funky stuff.
I just need to know if it is a file or directory, filesize and where to find the data of the file.

Just the path to the directory
