The Cliff Notes Version - Use the svg viewer extension found here:
I use a laptop running Windows 10, so my screenshots are based on that operating system, with chrome as my default browser.
A few google searches finally took me to an SVG viewer extension.
The very top one will work for most of you - if you are running Windows 10
If you don't know if you are running 32bit or 64 bit, go to Control Panel (in your start menu, choose windows system, control panel will be in there) and click on System & Secrurity:Next choose "View The Amount Of Ram & Processor Speed"
And your answer will be under system - see system type? Mine says 64 bit operating system, x64 based processor.
So I go to https://code.google.com/archive/p/svg-explorer-extension/downloads and download the 64 bit option. This will download as an exe file. Click on it to run it, follow the prompts.
And Voila -
For my downloads folder, this was immediate - I didn't have to do anything else, once it was installed, I saw previews! For my Dropbox folder (I back up all of my svg files and fonts in dropbox - sorted in folders by theme. That way when I do something stupid like break my laptop, I still have access to everything on my new laptop... ) I had to restart my computer.
You may need to change your view settings - at the top left of the screen - to "icons" if you are currently viewing in detail or list.
The 51 states SVG collection is free here - http://caluyadesign.com/freebie-gallery.html
I used it as an example simply because it was the first folder in my files. :-)
