My Galaxy Tablet 10.1 has almost 14 GB of storage. Currently, it's about 13.5 GB full of stuff, but I have no idea what. Recently, when I have tried to install some apps, I get an error saying there is not enough space.

I have tried to clear out all unneeded apps, and cleared the data from apps I do have. For example, the Firefox app had the most data, at about 100 MB, so I cleared it out, but the difference was negligible. All my downloaded apps combined are nowhere near 1GB in total.

My device is rooted, and I have ES File explorer, so I went looking to see if there were any log files taking up space, but after extensive searches, I can't find any log files more than a few kilobytes in size.

I can't figure out what is taking up all the space on my tablet. How can I clean it up?


If you go to storage in settings, you can see a basic breakdown, I'm guessing apps wont be the biggest, however look to see if pictures and videos; audio; downloads; cache or misc. is taking up a lot of space and click on the relevant entry to have further actions (clearing cache, deleting downloads, etc..).

If this option isn't available in settings (it is in aosp, but may not be in touchwiz), try searching the play store for a comparable app (see @user284oo6).

  • This may have worked. Under Storage -> Misc there was a file caled 0 that was 9 GB in size. I took a chance on deleting it, and my tablet seems to be running fine. I hope it wasn't important, but I can't imagine any one file that needs to be 9GB in size. – Questioner Aug 18 '14 at 15:48
  • It wont have been, the important files are hidden or in app data, if this solved your problem you could mark it as the solution, happy to help – ollie299792458 Aug 18 '14 at 15:50
  • I just wanted to give it a little time to make sure I hadn't broken anything. But if you're sure it isn't some kind of critical system file, I guess we're good. Thanks for the help! – Questioner Aug 18 '14 at 15:51

Clear the cache in settings >> storage then try. Sometimes Google Play will stop apps from installing when you have low space but if you clear your cache then you should be crime until you have to clear it again or when you actually run our of space.
