Sand, you're going to have to wait for a little while longer mate. I'm going to go over the ENTIRE php files tomorrow and fix/optimize + organize code and then add the functionality you want.
You want it to be able to rename the file to whatever name you specify, while retaining the file extension, right?

I'm also going to repackage the versions so people who are not going to use specific mods, can download versions that exclude those mods. That'll make the code more efficient and 'in use' instead of just lying around not being used.
