... could someone please explain some things to me. Now, i figured out what blue files are - as someone mentioned, they are compressed. However, there are other things that worry me. First off, here is a pic of Net File. I don't quite understand what that means, but since it's not empty, that bothers me. Second, my C drive is being shared, as seen here. and when i try to turn sharing off, this is what happens. Someone wanna explain this stuff to me? Thanks.
