Default [Q] Picture and videos from Sd Card converted

HI all,

I have a problem with my pictures and videos.

I have found all my pictures made with my s4 converted in a lower format. What I mean is my pictures were f about 3MB and now they are all saved in a folder called thumbnails and the approximate size is 55 Kb.

About the videos , I had to search deep in the root of the phone and found my videos in an hidden folder ( .thumbnails/movie) with the extansion as .lvl.

The file is very small.


Why this happend? is there a way to recover my videos?

Thanks a lot
