Viewing Sandisk files

After copying photo files to SanDisk Ultra Luxe USB 3.1 Flash Drive, I invoke the image viewer on photos in a folder. I can view the photo but cannot forward/backward to the previous/next photo. Also the files are not stored in numerical order. I have to copy the folder back to my PC to view the photos in sequence. Any suggestions?

The SanDisk vault is for security not convenience. :grin: Simply copy your photo files/folders to the drive outside of the vault for convenient viewing.

It works as you say it does. Thx, -Robert
