After literally weeks of searching I've resorted to posting here to find a solution to what I think is the most ridiculously simple problem that I'm surprised no one has ever experienced it before - I'm out of space on my iPad but I have absolutely no idea of working out where I am using my storage memory. You can read hundreds of threads talking about clearing up RAM and there are multiple apps that clear it for you, however I have not been able to find any useful app to show me how i am using my storage space. before everyone points out that iTunes shows you how you are using your storage i would like to point out that it doesn't. i tells me that i have 13gb of apps (god knows how) and it shows me how big *some* of them are, however these apps total about 2.5gb. some apps just do not appear here and i can only assume that the remaining apps make up the remaining 10.5gbs. Is it just me or is an app that shows you how much storage space each of your apps is taking up the one of the most basic functions iTunes should perform? and if it doesn't how difficult can it be to write one? Windows has been able to tell you how much storage space files are taking up for about 15 years! ok - rant over, any help with understanding where all my space is gone is much appreaciated - many thanks!
