Well my 2.5 yr old Celeron recognizes a Dig Camera as a drive when connected to the computer. If one has a 256Meg card, EZ enough to drop and drag into to the card in the camera or card reader which is USB connected. Then Xfer similarly to other machine. Win 95 I dont think will do it, at least 98 or 2000 version needed? This is for Xfer not for backup.
Did U READ my post? It says your Compact Flash or other leeeedle card will show up on your 'my computer' window when you connnect the camera or your card reader to a USB port. Then if its empty you simply drop and drag any files to it. Pull that card out when full, move it to the other machine to the inverse. You will simply copy or move the files from the Compact Flash to the other machine.
