I handle a pretty similar scenario. I manage files myself and don't use MobileSheets' sync features as I started long before sync has been added to Mobile Sheets.
I set up the same files and folders structure on all devices within the MobileSheets Storage Location. The local folder of my GoogleDrive is within the MobileSheets Storage Location, so the GoogleDrive app takes care for syncing that part to all Windows devices. A part of my huge library is outside the GoogleDrive folder because it's too much, but inside the MobileSheets Storage Location, so that MobileSheets can access everything. On Android devices I use Folder Sync Pro https://play.google.com/store/apps/detai...rsync.full to sync the local folder structure with GoogleDrive.
I use several MobileSheets databases, a relatively small "active" database with songs that I use on stage and that I carry around to sessions and rehearsals. And a big one to maintain a bigger part of my collection. I copy the MobileSheets databases manually to the devices where I want to use them. This allows me to have a smaller subset of songs on devices that I carry around and the big collection just on these devices where enough storage space is available.
