B4J Question Integrated Packager - standalone exe with all files included (as single file .exe)?

Hi
Using the Integrated Packager I can package a jar successfully to a folder (with sub folders and the exe) but haven't found a way to include all files in a single exe.
I was able to with Launch4j on java 8 but don't seem to be able to with jdk11

Hoping to be able to just have an exe I can distribute rather than an installer, as I would like to copy the exe into a folder and have it refer to other files in that folder without all the extra folders such as bin, conf, legal and lib needing to be added to the location (as below). Be much tidier if it was a single exe. (to use on Windows)


Any suggestions

Thanks
