How to store photos outside the vault

How do I place my pictures “outside” the Secure Access Vault? Just bought the Extreme Portable SanDisk SSD and placed a lot of jpegs into it - into the vault. . Now I realize I can’t se the tumbnails of each picture - only an icon list. I want to be able to view the thumbnails (icons) so I can work with the pictures. I saw a forum answer about storing the pictures on the drive outside of the vault - but I don’t see how to do that. I’m assuming the SanDisk Extreme has another drive I could place pictures into? If so, how do I access that drive? 

Thanks! John   

Just copy and paste your file into the main folder…right next to the INstruction manual PDF that comes with it. Folders do not go into the vault automatically.

I don’t like the Vault in that you cannot see the thumbnail - that is very annoying. And also, within a folder, you cannot navigate from file to file. You always have to exit first, and then go back. QUite annoying. I wonder if there is a solution to that!!!
