I own a Galaxy Note 2, and use ES File Explorer and Ghost Commander as my primary file explorers. I'd had this phone only a few months before I noticed that when I use the tool to analyze my internal storage (available in ES), if there are thumbnail files, it will scan MORE than 100% of my 10gb internal storage, then tell me I have, for example, 1gb free space, 1gb of pictures, and, say, 8gb of apps, then in addition to that, it will tell me I have as much as 16gb of thumbnail files, totaling out at 26gb, instead of the 10gb my phone says I have access to. I thought maybe this was a mistake, but when I navigate to the DCIM folder in Ghost Commander (DCIM is where ES tells me the thumbnail folder is), sure enough, there's a thumbnails folder that is 16gb in size, and when I delete it, it frees up ZERO space.
I know gigs of space is used by Android OS and bloatware, but I've seen no one stating this same problem, where thumbnails appear to take up space that doesn't EXIST... Is there a huge portion of my internal storage that does not count toward the available storage because it is reserved for thumbnails? I see articles saying how to fool your phone into thinking the external SD is actually the internal storage, but I don't want to do that; I'd LIKE to free up all this space that thumbnail files can use, but I CAN'T. Is this possible? I have not yet rooted my phone due to it still being under warrantee... Would rooting it enable ME to use this space, rather than it being reserved for cache?
Note: Yes, I DO have a ton of pictures on my external SD. But I'm not annoyed at how many thumbs are being created. I'm annoyed that when I delete them, I reclaim zero space on either of my SD cards.
Oh, and its probably also worth noting that, while I DO have tons of pictures, I don't have 16gb worth that I'm aware of, and my folder with the bulk of my picture files is hidden, thus not showing up in Gallery apps (which I assumed were usually the cause of thumbnail files in the DCIM folder)...
