Folder Indexes With Obsidian and Dataview

Using the excellent Dataview Obsidian plugin, inserting this snippet (below) into the note will create a table listing:

• all notes in the same folder as the note, and in all sub-folders, recursively
• all notes which link to the note
• all notes linked to by the note

Particularly when used in a "folder note" (a note which serves as the key note in any given folder), this is a simple way to create a kind of "section index" for that part of the folder hierarchy.

```dataview
TABLE rows.file.link AS Pages
WHERE
	contains(file.folder, this.file.folder)
	OR contains(file.inlinks, this.file.link)
	OR contains(file.outlinks, this.file.link)
	AND file != this.file
GROUP BY file.folder AS Folder
```
