    I saw a couple of other similar threads, but they all had strayed away from the topic, so I decided to start a new post.

    In my Nexus 7 storage, subtracting the space taken by music, pictures, videos, and apps from total available space DOES NOT equal my available space. I tried restarting already, no luck...

    Others seeing similar issue? Any solutions or idea for causes? Thanks.

    The storage menu seems to only calculate stuff in specific folders, so stuff outside of those folders won't be included. You should use a file explorer to calculate the space used by your /mnt/sdcard/ folder and I suspect that this will account for most of the difference.

    The discrepancy is about 1.5 GB. Also interesting to point out, it seems that the bar graph on top of the storage page is indicating the correct available storage space, which conflicts with the numerical values shown below it.

    I had this problem as well and made a topic last week about it, just turn the device off and on again and it should show the correct space available. Mine was off by about 5GB!

    I was able to resolve the issue so I wanted to post the solution for anyone else out there with the same problem. Turning it off and on didn't work for me...I tried it several times too.

    The solution was rather simple, I did a factory reset through the settings page. It was a bit annoying to get everything back, but google does a good job of returning the tablet to the previous setup. All apps automatically downloaded onto device, I only had to redo a few of the settings. After that, the space has been shown correctly.

    Yes, on mime too it seems the graph is more accurate than the numbers.

    The cache is not calculated under storage so over time it will seem inaccurate but it is correct about the free space. If you get a cache cleaner you see what I mean.

    I had this same issue and the poster above is correct. I downloaded a cache cleaner from the Play Store and I had a ton of cached data from Google Music that was causing the storage #'s to be different (over 1.0 GB difference). I would suggest trying a cache cleaner prior to doing a factory reset of any sort.

    I have the same issue here, that seems needing an scandisk utility, I still looking for one, but of course the issue is not a cache or hidden file, I'm working under linux and I mount my sdcard as a regular harddisk, and I'm completely sure that the available space is being reported incorrectly.
    The system doesn't scan the disk to see the used space for the available files then subtract from the storage capacity to get the available free space, but it just asks the partition table and gets fast respond to the available free space, which seems giving wrong report after a device system crash or something.

    But the above bar showing the statistics according to the whole files capacity in comparison to the total space, and this is why it gives the correct visual representation for the available space.

    Also, I want to add that the hardware reset doesn't consider to be a solution for this issue, you may have your device crashing at least once or twice a week, which will most probably do the issue again, where resetting the device will be nightmare if you are going to do it at least once per week!!

    There are huge invisible files somewhere out there, which takes all space. This is mostly cached and temp files. I tried different cache cleaners from the Play Store, but they didn't see these huge files either.

    I finally solved the problem using application called "My Device Storage Analyzer". It shows you your storage usage, and it sorts all files by size, allowing you to find huge files and delete them manually, one by one. (I found about six files about 1 GB each, and when I deleted them I freed up about 6 GB).
