I know how to create a folder with java, but I dont know what the .minecraft directory would be saved as. For example, my .minecraft directory is saved under "C:\Users\Daniel\AppData\Roaming", but obviously that wouldnt be where it is located for other people. Flans Mod and Shaders has did this

Why do you want to do this? Usually you don't need to create a new folder. Please describe why you think you do, there might be a better solution.

Otherwise: Minecraft.getMinecraft().mcDataDir

 

Thanks, Its working now with that method. Im making a music mod so people can import their own music into minecraft

Can't ResourcePacks do this?

 

Yea, but its

 

1. Not going to override normal records

2. Have headphones so you can walk around and the music doesnt get quieter

3. You can pause, stop, rewind, shuffle, speed up and fast forward

I think the point is that music files should just be sound assets and there is already a standard folder system for mod assets.

Stuff in your resource folder (assets) can be overridden by resourcepacks (old texturepacks). This is all done by minecraft, so it just works without you doing anything.
