Simple File Extension Sorter

Sorting tool that sorts by file extension and puts it in folders (that are named by extension)

Usage:

-p (prefix) - sets prefixes for folders like '(prefix)txt' or '(prefix)doc'

-n - create folders named by just extensions

-r - sorts unsorted files in already created folders using previous prefix

-h - shows help message

-c - unsort, bring files back from folders (also deleting folders)

I forgot what i wrote and i dont understand my code lol, there is still some work to do (like what to do when there is already a file with same name in folder) so i need to do something
