How do you repack idx files?

[SSJVegetaTrunks]

I made a couple changes to the sounds files using the idx tool made by Vercingetorix (version 0.97), but I haven't a clue how to repack them. Do I use xidx.exe, or xidxShell? Whenever I try to use the exe file, it exits automatically after about ten seconds, and I don't know what I'm supposed to do with it. I don't know how to use the shell, either.

Please, someone explain to me what to do!

Please, does anyone know? I have no idea what I'm doing wrong, and I've been struggling with this for days!

I'm pretty sure you don't need to repack them, but there are instructions with the idx extractor.

I don't understand the instructions at all. And, I heard you do have to repak them.

The instructions are simple for extracting, but don't seem to explain how to repak.
