I had an issue where my MacBook Air would not start a couple days back, so I reinstalled the OS. I ran the reinstallation from the recovery partition. Ever since then, almost all of my files show as type "Document", as you can see. Even music does. I do not understand why this is. I even tried reinstalling again and have the same issue. Does anyone know of a fix, this is extremely annoying. I did not have this problem before the reinstallation.
