A _space_ is SilverBullet terminology for a workspace, or project. [Obsidian](https://obsidian.md/) calls this a vault, [LogSeq](https://logseq.com/) calls it a graph. You may think of it as a folder or a directory — because in practical terms, that’s all it is.

Feel free to back-up or manipulate your space;s folder and its files with whatever tool you like — you don’t have to use SilverBullet exclusively. You may want to turn your space’s folder into a git repository, for instance, and do version control and back-ups that way — in which case you may appreciated the [[🔌 Git]] plug.

## Pages
All pages in your space are stored as files with a `.md` file extension. While _folders_ are not really a first-class concept in SilverBullet, you can create pages with a `/` in their name, which will (under the hood) automatically create a folder structure to match it. So creating a page named `people/John` will ensure a `people` folder in your space’s root, and put a `John.md` file in it.

## Attachments
Attachments are kept alongside the rest of your files with whatever file extension they have (e.g. `.jpg` for images, or `.pdf` for PDFs).

## Folder Lay-out
Every space in SilverBullet at the very least has an index page (by default named `index.md`) and a SETTINGS page (named `SETTINGS.md`). If you install custom [[🔌 Plugs]], these will be kept under `_plug` in your space’s folder.
