In Obsidian, you can have more than one vault. ## Opening a new vault To open a new vault, click on the icon in [[The Obsidian UI and settings#The toolbar|the toolbar]]: ![[ui-open-another-vault.png]] Create or select another vault. Another instance of Obsidian is opened. ## Why have multiple vaults? Here are some reasons to have multiple vaults: - You want to [[Sharing your notes|share]] a vault with others, but not all vaults. - Security: you could have a high security vault that doesn't use [[Community plugins]], and a low security vault that does. - Create a new test vault for experimentation without affecting your real notes. - Create a vault to contain types of assets (such as images, videos, audio, PDFs) that you don't want to clutter your main vault with. - Keep a reference vault of content you didn't create. ## Why have one vault? However, there are limitations to having multiple vaults. - You can create links between vaults, but they do not update when the files being linked to update. - You can't see [[Backlinks]] from another vault. - The [[Graph view]] is per vault only. - Having multiple vaults adds complexity. ## How to link between vaults Open up a note, right click on the tab, and select *Copy Obsidian URL*. It looks something like this: `obsidian://open?vault=o4e-06&file=00%20Obsidian%20for%20Everyone%20course%2F00-02%20First%20steps%20with%20Obsidian%2FWorking%20with%20multiple%20vaults` In the other vault, type it out in this format: ``` [text here](paste the link here) ``` Like [this](obsidian://open?vault=o4e-06&file=00%20Obsidian%20for%20Everyone%20course%2F00-02%20First%20steps%20with%20Obsidian%2FWorking%20with%20multiple%20vaults).
