The External Attachments Plugin provides support for importing tiddlers as external attachments. That means that instead of importing binary files as self-contained tiddlers, they are imported as "skinny" tiddlers that reference the original file via the _canonical_uri field. This reduces the size of the wiki and thus improves performance. However, it does mean that the wiki is no longer fully self-contained.

This plugin only works when using TiddlyWiki with platforms such as TiddlyDesktop that support the path attribute for imported/dragged files.
