This plugin provides support for importing tiddlers as external attachments -- it only works on platforms such as TiddlyDesktop that provide the required "path" property with imported files. Using the plugin 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
