Wiki.js doesn't have a folder structure in the traditional sense. You never need to create folders in order to create new pages. Instead, you create pages directly at the path of your choice.
For example, in order to create a page at
/universe/planets/earth, you don't need to create the folders
planets in the first place. They'll be inferred automatically.
This system allows for greater flexibility and less dependencies between pages. However that doesn't mean you can't use a traditional folder system should you want to. The folder structure is still available when creating and moving pages. The only difference being you don't have to manage folders, they are inferred automatically from pages paths.
The breadcrumbs bar shown on top of every page is generated automatically from the path.
Tags are a great way to categorize your pages and easily find related content. They are a much leaner alternative to using a complex system of folders to categorize your content. Tags are simple labels attached to a page.
Multiple tags can be added to a page.
For example, for a page about the city Montreal, you could add tags
north-america. These tags can then be used to quickly find the page afterwards. By browsing by tags
cities, the page Montreal will come up in the results because both of these tags are present on the page.
More tags can be added or removed from a page at any time.
Use the Browse by Tags link (located next to the search bar, or in the navigation menu) to see a list of all tags available in the wiki.
Select one or multiple tags to view a list of pages matching the selection.
