Document Creator in Batch

Once again, I made this instructable because it could be made. You don't need to use it or even acknowledge its existence.

Now, onto the specifics.

I made this "program" a rather long time ago. Well, at least the first version. It was originally called batch maker, but now it is called batch maker.

It was inspired by someone who said on my question (I delete it a while ago so this is not an exact quote) "Inspiration for batch files", where I asked for something to make with batch files. "Make a batch file to make your batch files." is along the lines of what he/she said.

Now, the features:
1. Can make all types of files*
2. Can delete, rename, edit and create files.
3. It has been added to my Mega_Menu instructable.

Now onto the code:

* Can only make files with extensions of two or three letters (Eg: .exe, .py, .bat, .txt). If no extension is added (or an extension with over 3 letters is recorded, ".txt" is added onto the end.

That's it. Once again, tell me if you need ANYTHING (emphasis on anything).
