You can restrict the content displayed on the overview pages or in the search results. To do this, use the filters. They help to make your overview more streamlined and you can access the content you’re looking for more quickly. You can find the filters in the area on the left. Every overview page offers various filter options, they basically all work in the same way. By default, the filters are set on the overview pages so that everything is initially displayed to you.
The filters on the left-hand side of the screen indicate how much content is hidden behind the filter (e.g. 6 behind the type "Files").
