Paths. and Optimal paths?

[DeathOfTime]

I can customize the path of most the files for the launcher. Yet the path for the launcher options and data are still stored in appdata, unless I use a dos bat file to change its position.

The paths are absolute and I don't know how to change it so it will always look in the current folder that the launcher is in. Instead of whatever path is set in the options.

..\FTB
instead of:
C:\0 Installed\Minecraft\FTB

I used to be able to force minecraft to always use the folder it is in for all its data. I have never been able to manage this with the FTB launcher, without a lot of manual setup. I can't figure out how to do this automatically with minecraft anymore either.

The main reason I am asking for this is that I tend to setup the game on my computer then move it around as needed. Copying all the data to others computer or to flash drives as I want to. My brother, and my girlfriend both have trouble setting up programs at times. So I would usually set it up on my computer then copy it over to theirs. Deleting my account information off of it and using their account information for their games.

Sorry, got it working. Notes on it below in the edits.

On a similar note. What would be the best place to put the FTB launcher and run the packs from? I originally had it in my documents folder. It now complains about that. So I place it in a folder just off of the root drive.

I know that this launcher is being setup to be easily used by anyone. Would be nice to see more advances options though for those that like to tinker.

Thanks for your time.

Edit:
Weird launcher behavior. I think I got it figured out though. I launch it from a bat file that contains the following code:

set APPDATA=%cd%
FTB_Launcher.exe
Exit

Then place the %CD% in FTB options as the path.

Then it places all the launcher data in the same folder as the launcher and the pack data in a folder off of that named %CD%. I don't know why that is working though.

Edit: doesn't work with Agrarian Skyes. Trying .\packs for the path now.
Edit: .\packs seems to be an acceptable path to the mods packs I have tried.

Edit: Found another folder that FTB creates. That I can't figure out how to get directly in the same folder as the launcher.
