I have an 8GB Nextbook7 running Android 4.0.4. Recently, I discovered that I have 2 files named .thumbdata3... eating up all my internal space of 5+GB. These files are found in the .thumbnail folder under the DCIM folder. I have read on the internet that these files are produced by Android Gallery, but there is a bug in the OS that causes these files to grow so large and max out all the available internal storage space.
I have tried deleting the files, but they come back. I have tried writing small text files and saving them with the name .thumbdata3... as in the problem files, but that does not work either. I have downloaded an app called Thumbnail file deleter, which deletes the problem files, but the files will rebuild themselves again until the space is maxed out.
Does anyone have a permanent cure to this .thumdata3... problem? Any suggestions appreciated. Thanks.
