So, I'm trying to convert a bunch of OGG files to M4A using a program called Super. Only problem is that this program adds the extension you're trying to convert to after the source extension.

So, if I convert a file named `Keyboard.ogg` to an M4A file, it converts it to an M4A, but the resulting file name is `Keyboard.ogg.M4A`.

What I want to do is when the conversion finishes, I want to run a command or batch script on every file ending in `.ogg.M4A` so that the result is `Keyboard.m4a` instead of `Keyboard.ogg.M4A` (The file extension should be lower case since a program I am using to develop a video game requires both `.ogg` and `.m4a` files for exports (since it uses OGG for PC exports and M4A for Mobile exports) and I think it might be case sensitive.)

I have tried the solution [here](https://stackoverflow.com/questions/3215501/batch-remove-file-extension), but when using `%%~nf` it only removes the .M4A part (instead of the `.ogg.M4A`) and if I were to rename that I'd be back at square 1.
