I have a 32GB 4S. I recently received a message that my phone is running out of space. How do I know what documents and data are taking up space on my phone? Obviously some things are easy...I know my music, videos and Spotify are the biggest culprits. And I also use podcasting software and the Nook app. But with some of my apps I wasn't sure what was causing the large data store. For instance I use TweetDeck. The size of the app is 2.5MB. But the total usage on my phone was showing 430MB. I ended up removing the app and reinstalling it to reduce the size. But what is all that data and how do you remove it without having to uninstall and reinstall the app? I use TweetDeck a lot so I don't want to have to keep uninstalling and reinstalling it to reduce the app size. Another example is the EuropeanTour golf app. I hardly ever use the app but it says I have 17MB worth of documents & data stored on my phone. Is there a way to tell what that is and how to get rid of it?
