Recently, I noticed that on the files on my external hard drive are not shown in Finder. All folders can still be navigated, but the files are not visible. When I check the contents of these folders in terminal, I can see the files are still on those locations and can also be opened with VLC for example.
Does anybody know what the issue could be? I only found one similar question, where they suggested that the com.apple.IconServices was causing the problem, however the proposed solution did not help in my case.
I am working on OSX 10.8.5.
