Both of you made it much clear thanks, I not saying like how windows files are but rather if I wanted a certain program you would use the Synaptic Package manager and Software Manager and type the name and install, yes? But what if it's not listed there and the company website doesn't have a .deb file? I will later when I have more time learn about PPA, I don't want to get too much in my head, I'm trying to take it slowly so it can stick in my head lol
