sorry i was busy at work last day
there is like a thousand of empty folders in the SD card and there is too many .tmp files
i tried to use SD card file recovery but the result was Zero
it's weird that the SD card is 8GB and there is just 5.6GB free space with empty folders and there is no hidden files
should i format the SD card ?
i found something interesting ( wp_ss_201307011_0001.tmp )
now how to change the extension to jpg
what a shame
