Hello, I have an IPad and I have attempted to reclaim as much space as possible as I am running out of space. However, in ITunes I can tell that the overwhelming majority of space is dedicated to APP data, but I really do not know why they take so much space. I really do not want to delete the APPs, but merely reset them to original installation data as I suspect that most data consists of temporary files, caches etc. Is there a way to identify how much space individual APPs takes, and if so, reclaiming the space to clean original installation date? Naturally I do not want to uninstall and reinstall every single app, especially since I do not now how much space individual APP takes, so is there a way? Thanks in advance.
