Video clip on the map (adventure dialog).

In general, screenshots are not needed to demonstrate the creation of a directory. In the Dialog Scene window, right-click, then select "new root folder" to create a new directory. This window already contains the directories: DialogScenes and Maps. After restarting the computer (this does not happen when entering or exiting the editor), the directory is not visible in the Dialog Scene window. However, it is present in the map archive. I filled in the fields exactly as in the first post. This raises some questions. Where should I create the directory, and how should I create it? Is it necessary to specify the path to the video, either in the map tree or elsewhere, or where should I specify it?
