Hello, I have an Acer Iconia A500 running Android 4.03. Everything is working good except that recently my available storage has dropped to just 4.5 gb. I ran an APP named "File Manager HD" and performed a "Storage Analysis" that said a folder "/mnt/sdcard/DCIM/.thumbnails" was using over 80% of the total storage. This folder contains 120 files, 118 of which are jpg's at about 25kb each, but 2 files use 10.25gb. (1) ".thumbdata3 -- 1967290299" Dec 1, 2012 21:08 at 4.38gb, and (2) ".thumbdata3 - 1763508120" Dec 10, 2012 14:08 14:08 at 5.87gb. The APP "Image Viewer" seems to show the contents of these two hugh files is a small picture of each of the other jpg's in this folder. As a side note there is another folder "/mnt/sdcard/Pictures" that contains 400 to 500 larger jpg's including the 118 mentioned above. My question is what are these two hugh files and can I delete them freeing up 10.25gb of storage?
