Folder sync: keep a NotebookLM notebook current on disk
Short answer
Folder sync writes a NotebookLM notebook to a folder on your computer and keeps it current. You pick the folder once; later syncs write only what changed and never delete your local files. It suits Obsidian vaults and backup drives. It is a Pro feature.
