While it’s not directly supported by the interface, it’s in fact possible though a workaround described in an article on this forum, under the section called 'Other Sync Services": Dropbox Sync
The gist of it is that Dropbox sync is currently the only way to store your Findings library outside of the app container, for the purpose of syncing through a specific folder in Dropbox. But I built a ‘backdoor’ for testing purposes that allows to create a “fake” Dropbox directory that the app will accept. I added it as a way to test other sync services like Google Drive, or storing on an external disk or network volume (assuming it’s fast enough), but it can also be used to store anywhere on your disk. And that should answer your needs… Let me know how it goes!
