Duplicate Finder

This function will scan all files in current folder and sub folders and build a list about duplication in default mode. You can use switches to choose one of the following options to manage files:

DisplayOnly / Manual / Auto / DefendedDirectory / Save / ReturnObject

Important note.

I did not spend too much time on testing of this script. So use it carefully and make backup before run.
