This is a self explained source code for a very useful tool, a downloaded files manager which will help you to bulk process your downloads, renaming the files for removing annoying chars and strings, years, and unwanted added comments as : ( by the big ripper ) from the file names, leaving you with the clean file names we all want.
In this tutorial you will have nice examples on how to work with :

Downdloaded files manager Tutorial
Author : BlackRabbit ( Abel Carabajal )
Date : 2012-05-13
Version: 0.1
Purpose :
Organize downloads, rename and Copy/move downloaded files from downloaders incoming
files folders to designed repositories, and then Manage repositories, using file type
criteria,
and incrementaly compare and syncronize with back up repositories
In next version :
- File distribution to folders by file extension
- File compare in between repositories
- Repository to .csv file
- File type config strings
- Open / Save project
