<Menus are complicated in Xfce, so this slightly edited post by ToZ on the Xfce Forum is very helpful>
There are 3 places where the xfce-applications.menu could reside:
- the Xfce default location => /etc/xdg/menus/xfce-applications.menu
- distro-specific defaults => (e.g. for Xubuntu it is /etc/xdg/xdg-xubuntu/menus/xfce-applications.menu
- user configurable location => ~/.config/menus/xfce-applications.menu
It is this user-configurable location that anyone who wants to make fundamental changes to the menu should be using. The example will be wanting to have a new category called "Multimedia-Editors"
Let's start from the beginning:
Copy over the default file for personal editing and use:
cp /etc/xdg/menus/xfce-applications.menu ~/.config/menus
Create the ~/.local/share/desktop-directories/Multimedia-Editors.desktop file:
Create the ~/.local/share/applications/mediainfo-gui.desktop file that has its categories line like:
Add the directory information into the xfce-applications.menu file (I'm inserting it just above the Development section):
This should create the category for you.
