Can't find pictures, using Vista, folder gone

Hello,
I need help finding where my computer put my pictures. I have never put my pictures on this computer before, and I think it has something to do with Vista. I put my sandisk memory card in the computer, brought up the pictures, but couldn't find a save option. I created a folder and titled it, then manually moved each picture into the folder. I was never asked if I wanted to delete any pictures. When I took the memory card out and put it in my camera, the pictures were gone. When I looked in my folders and documents I couldn't find the folder I created. Not in recent documents, or in pictures, or anywhere. I am not sure how to do a search or recovery either. I am sick about losing these pictures. Did I erase them accidentally? Where could they be? Thanks!
