Thank you, still looking, about to give up.

Thanks Rich, I think that is my last option. I've never seen or heard of this before, they just vanished from everywhere.

Thanks again.

Thanks Wendy. I could probably get the file numbers since I haven't used the SD card since. I've searched all the obvious places on my hard drive. I even downloaded one of the lost file recovery programs and scanned my SD card. I'm guessing I need to do the same on my HD. It just seemed odd that the only ones missing were from the card in my D700 and the images shot with my D200 were still there.

I shot a model last Saturday afternoon and started editing the images in PS CS5 that evening. Over the next 3 days I edited 8 or 10 images and on the 4th day all of the images that I shot with my Nikon D700, approx 150, where gone. I also used a D200 to take 6 other shots using on camera flash, these shots were still in the folder that was created using PS Bridge. Only the shots taken with the D700 were missing. I scanned my hard drive, my SD card, and looked every where I could think of but was unable to locate. I use a Mac Book Pro for all my editing. I did leave Bridge open for a few days with this particular folder open as well and was wondering if this had anything to do with it. Any help would be much appreciated.
