I have noticed that my memory space is starting to fill up and so I have been trying to make sure I delete all old messages, emails, call history, apps I don't use that much ect. I clicked on quick office which I never really use but noticed it has alot of stuff on it. I guess everytime I download stuff it is also stored on that app? I don't know alot about where stuff goes. I went in to settings to see if I could clear the cache and it did not have anything but there was alot of data. If I cleared all the data would it mess up all the apps and stuff I have downloaded? There is stuff on there from apps I have deleted also. But I don't see anywhere where you can delete things from the app itself.
