I have 26 jpg files in my dcim/.thumbnails folder but only 3 SPMO files in my dcim/.thumbnails/SPMO folder and "1" files in my dcim/Camera folder. I just took the picture in the Camera folder and no new SPMO file was created. I want to clean out the SPMO folder, since they don't seem related to anything. My question is, what creates them? I understand the file has something to do with quick access but I use the "Gallery" app and I don't think it uses SPMO files.
