USB Export and additional files

How transfer to USB Flash with USB Export option some additional files used for my dopus config. Example: I have some functions on buttons that use external small exe files. How transfer it while exporting to USB?

If you had some sort of file manager you could use it to copy the files to the USB stick...

I meant automatically copy it while operating with Backup&Restore - Export to USB Flash Drive.

You can put things in the Scripts config folder (create it if it doesn't exist), described here.
