If a program is not listed in the Application folder, is it safe to assume it is not installed? The reason I ask is because I downloaded Gimp from Cnet, "installed it", tried it out for a bit, and decided it wasn't for me. However, during this process, I never dragged Gimp into my Application folder, and left the .dmg file on my desktop. Do I still have to "uninstall" it even though I never dragged it into my Application folder? I deleted the .dmg file and did a search on Finder for Gimp and found nothing, so my assumption is that it is 100% gone from my system. Thoughts?
