Is it safe to clear my downloads folder? Basically, it has become very large (~20gb). I want to create some more space because my hard drive is partitioned. Basically, what I'm wondering is, if, for example someone sends me a song. I play the song through itunes. Doesn't the song then get copied into an iTunes folder? Assuming it does, does that mean there is a duplicate file in the downloads folder as in the iTunes folder? Otherwise, do I have to manually go through my downloads folder and decide whats needed and whats not? Thanks.
