Locating music files

Hi everyone, newbie on here looking for help - I have music files scattered all over the place on a laptop, external hard drives and a desktop pc. What I want to do is try and locate them all so that I can put them all together in my iTunes library. Is there a quick way to search for these files please and how do I transfer them all to my library once I've located them, many thanks
