Embeddedcmddirs argument for full path

using embeddedcmddirs {o|noext} returns last part of path, what is the argument for full-path please ?

You can find them in the button editor menus, or in the manual.

Thanks, and can library paths be resolved to normal paths ?

What are you aiming to do?

Set up menu of image folders - click on folder and it automatically sets the folder for background image slideshow.

Try Resolve.
