Okay, so I have downloaded music that I have saved in a floder that I created (User - Music - Downloads). Also, if I go into my music folder and go into iTunes - iTunes Media - Music, copies of all my music are also in there. As a test, I went into my downloads folder and deleted something I didn't care too much for, Joan Jett, and then deleted it from my trash. I then went into my iTunes and it was still there and would play and was also still in my Music - iTunes - iTunes Media - Music folder. My question is when I import music into iTunes, does it make duplicates and get the information from there? Because I'm looking to clear up space on my computer, and if that were the case, I could clear up about 40gb of space by deleting my Music - Downloads folder seeing as iTunes gets all the information from the other folder. I want to be 100% sure first though, because if I were to lose all of my music I'm not sure I would live! Please help me, thanks!
