Is there any photo organizing app that organizes pictures into actual OS folders, like iTunes does with music? I don't like the database storage concept since there are certain risks of corruption, and also I like the control over my files because it's easier to backup and move things around. And also, it just creates a duplicate which doubles the required storage. I've googled and searched the forum and I couldn't really find a solution. I think only Picasa can do this but Picasa interface is quite cluttered. Any suggestions?
