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.

## Quick facts

## Steps

1. Install [NotebookLM Ultra Exporter](https://chromewebstore.google.com/detail/notebooklm-ultra-exporter/afchokljnhhggkhedfbmkcmdagjmjchj) in desktop Chrome, then refresh any open NotebookLM (Gemini Notebook) tab.
2. Find it here: Archive dialog at the top of the Studio panel, folder option.
3. Use it on one item first and check the result before running it on many.

## What it does

- Writes notes, chats, Studio text and source text as files.
- Skips files that have not changed since the last sync.
- Can use the Obsidian layout with frontmatter and a wiki-link index.

## Limits to know

- Sync is one-way, from NotebookLM to the folder.
- It runs when you start it, in a browser that supports folder access. Otherwise use ZIP.
