Blackjack II - MicroSD Card Help!

I Have a blackjack II. I Got a Kingston 2gig microsd card and transfered all my pictures and videos to my microsd card, I Than plugged my Microsd card up to the usb card reader on my mac, I open the folders to view my pictures, and they are labeled like this "PIC-0264.jpg.47ad30cb.menc", I Believe the .menc is some type of encryption used on Window-Based Products?, I really would like to share my pictures with all my friends, and would not like to lose them. Is there any way i can get rid of the ".menc" or decrypt or whatever i have to do to open these files on my mac? I would really be ****** off if i am unable to do this, and lose my pictures from the whole summer.
