Ok, before I can help you I need a list of information on this tool you're making.
This list includes:
The project's purpose
How far you are in the project
The types of files it can read and write to
What you want me to help with
Once you've got all that done and sent to me, I will start helping you. If I have offended you, I really haven't meant to it's just that I need organization when it comes to stuff like this.
