Raidrive is a great "plug and play" utility for mounting. Unfortunately it uses a universal oauth key, therefore if you have a large Plex library you can run into API bans. If you want plug and play with better API management (use your own API keys) and are willing to pay, check out netdrive. If you want a free utility that can do custom API but is more complex to setup, check out rclone (they have windows binaries too.) That said, if it's working well for you, "if it ain't broke done fix it!"
