You can recover lost photos,videos from memory card or memory stick of your camcorder with this
1. Do not save any new photos and videos into the memory card or memory stick.
2. Connect the memory card or memory stick with computer. You should see it shown as a drive letter (like H:) in My Computer.
3. Download recovery software, recommended one is Tenorshare Data Recovery (simply because i was using it and it worked)

4. Install and open the program, select your memory drive, and click 'Start' button to start scanning process which will find your lost photos and videos.
