The "Job Name" is the name of the file. It is embedded in the file and you need to do a "Save As..." to set it.
You can see what the job name is by doing an ASCII export and then opening the .ASC file in a text editor.
Thanks yes the save as itself works. However by doign that it created another folder below the folder the pcb file is in with same name of pcb, folder is empty?
Why does it do that? If I delete that folder, as it has nothing in it, when ever I export an ascii file it keeps creating that blank folder?
