10.2 Attachments

It is often useful to associate reference material with an outline node. Small chunks of plain text can simply be stored in the subtree of a project. Hyperlinks (see Hyperlinks) can establish associations with files that live elsewhere on a local, or even remote, computer, like emails or source code files belonging to a project.

Another method is attachments, which are files located in a directory belonging to an outline node. Org uses directories either named by a unique ID of each entry, or by a ‘DIR’ property.
