I tried that several times & even downloaded another viewer. The only thing worked to download part of the videos was suggested by the computer tech guys that set up my new laptop. I had to insert the card, open the file explorer, click on MyPC and then double-click on the SD card. I then had to search for the videos and use ctrl-A to select all, then ctrl-C copy them and ctrl-V to paste them into another folder. Very cumbersome lots of steps - isn't there a more efficient better way?
