 ##### `slashSubstitute`
 The patterns represent Unix file paths, and a `/` therefore indicates a new directory. You may freely use directories in your paths, but titles or descriptions may contain a `/` that is not supposed to create a new directory.

+##### `album.extractSingleItem` and `extractedLabel`
+Some albums contain only one image or video. By setting `album.extractSingleItem` to `true` (default), the item will be saved in accordance to the individual item patterns rather than the album patterns. An extracted item will inherit the title and description of the album if it has none of its own. Extracted items can be marked with the `$extracted` boolean variable, of which the display value is set with `extractedLabel`.
