I am running mac, and made a file, transferred it to my Windows 7 computer, and the icon isn't there. I took my icon file, and tried to change it, but I could not figure out how. I want it so that I can change the files icon, but only that files icon, not every file of that type. I also want it so that when others download it, they see the icon too. Two things I must say though: I want instructions, not a link. Also, I want the simplest, that follows all of my requirements. Please help me, thanks.
P.S. If it helps, it is a .gba file.
