Sony is pretty adament about users not maniuplating individual NXCAM files. Aparently doing so makes the media unreadable by the camera. Windows users need to use the Sony CMU (Content Management Utility). Unfortunately there's no Mac version.
I suspect in your case, you'll need to connect your flash drive to the Mac directly, rather than connecting through the camera. What kind of flash drive are you using?
