There's a firecracker driver for Hashi's Nomad. Haven't tried that driver, but nomad isn't bad.

It has problems on shutdown and few months ago didn’t work properly with namespaces, haven’t checked recently. Can be worked around…

http://www.fastrawviewer.com/ or On1 Browse are good fast raw viewers on windows. I use them to 'manage' my library as I use a mix of raw processors and don't want to be tied to them for my workflow.

Took 5k pictures today so I'll try them out now. Thanks!

I just use the insync client - much better than the native Google Drive client anyway - even allows for multiple accounts, and selective sync (even subfolders)
