Tags are keywords that you can assign to a file. This feature is available in the component Report Designer under the Files tab. 

By right-clicking on a file, you can add tags using the context menu (see arrow in image below). You can assign multiple tags to a file to make it easier to find.

You can edit and sort existing tags with the Tags button in the menu bar (see marked area in image above). Clicking the Tags button brings up the Tag Manager:

Here you can select files by Context, Type, or Tag.

With Jedox Mobile you can use specific tags.
