1. Create four nested folders.
   "Invisible-01\Invisible-02\Invisible-03\Invisible-04\"
2. Hide the first folder: "Invisible-01" and confirm the others will be also hidden by supperior
3. Create another four nested folders.
   "Visible-01\Visible-02\Visible-03\Visible-04\"
4. Create "Article-01" under the "Visible-04" folder
5. Move the "Visible-01" subtree into "\Invisible-04\" folder
6. Confirm that "Article-01" will remain visible
