It opens Server Explorer that lets you browse files on the server, see file preview, create new folders,
delete existing folders and files, and upload new files to the selected directory on the server.

Server Explorer displays the files under ~/UltimateEditorInclude/UserFiles directory. There is a built-in
Templates directory under it. You can customize the content of the Templates directory by adding your own
custom HTML files and they will be automatically displayed inside the Server Explorer window.
