Thank you for letting me know that.
I deleted video file accidentanly. I used Recuva ( free version). I could get most of data back. Only a few more data is still left. In free version. Indicate as poor quality ( orange colour). I could see 3 secondin 2 min. video. I really want it because of my kids memory. I wonder if I use recuva professional, I could get better result or not. I would appreciate any advice/help.
