Can zx_* folders be deleted ?

[FFMan]

Some of my project areas have tens of folders starting zx_ that appear to be empty.

Do I need to keep these ?

thanks

They are temporary working directories that are supposed to be deleted. You can delete them and then let us know if they reappear. If they do, we'll want to see the contents of your User Properties file and the .pjt file to see what combination of compiler options are being used.
