I made some custom launchers. Mostly for Wine programs, but also for Maple, etc.

Is there a way to save the icons and the commands so that when I do a reformat I can restore them?

I really just need to know where this stuff is saved, and I'm coming up pretty blank.

I was looking through /usr/share, and ~/.local/share
but both seem very disorganized. I feel like there has to be a central location where all this is saved...
