As the title suggests, I have duplicate/multiple copies of applications in my Mobile Applications folder. My initial assumption is that is has something to do with application updates not overwriting the older versions. I have no idea why it's creating multiple copies for some & not others. I don't want to delete any of the duplicates until I have more information. I also found a thread where this issue is mentioned, so it's happening to at least one other person. http://forums.macrumors.com/showpost.php?p=5835167&postcount=8 Does anyone else know anything about this? Are there any other people experiencing this issue? You should check & see if you are. Here is a picture of my Mobile Applications folder so you can all see which copies of my applications are multiplying.
