Thank you. But my issue is the file I need to move in is actually synced automatically, and copy&paste breaks that syncing.
More context: I’m using the “Citations” Plug-in, which requires a feeding of a .bib file, and I use the ‘automatic-export’ feature from BibLaTex (a Zotero plugin) to automatically sync my most up-to-date citation files for the Obsidian Vault to extract.
And now, my Zotero cannot open this magic folder, which makes this whole workflow obsolete.
I guess I’ll have to wait till this problem is resolved by the developer, in order to ‘sync bibliography’.
