You can use Data Recovery Software in order to recover your lost or deleted files from the system. With the help of the software you can be able to recover audio, video, picture and document from the memory card. A month ago, I accidentally deleted some of my important pictures and video from my memory card. Later, my friend suggested me to use Remo Recover (Windows) - Media software from which I was able to get back all of my deleted data back. You can also
recover files from corrupted SD card. You can
download the demo version and just check for the recovery results.
