OS X Lion All Files Showing as Type of Document

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.

Solution 1:

Have you tried repairing Disk Permissions using the Disk Utility when booted off your Recovery Partition?

Solution 2:

I had a similar issue with video files showing up as Documents.

I fixed it by getting the app Onyx.

Once you get it (make sure it's for the OS X version you are running since latest version is for 10.8 only), go to Maintenance >> Rebuild.

I checked all options and I remember checking "Display of Folders' contents" particularly.

Next, I clicked on Cleaning tap and performed most cleaning scripts.

After that, I did the other maintenance scripts in the app including repairing permissions and restarted.

That took care of the issue for me. Hope that helps.
