Sending Design Files Without A Plugin-in

Hello,
Using Ver. 5.1.12 in Windows 7. Machine is too old, I cannot upgrade the OS. Can designs be sent to PCBWAY without using the convenient PCBWAY Plug-in? Looks like I would have to upgrade KiCad to at least Ver. 6 to be able to set up the Plug-in, but Ver. 6 won’t run under Win 7.
Is there a procedure to upload design files, or is this approach not worth the trouble?

Sure, it’s the way it was done by oldtimers before plugins were developed. PCBWay has instructions on their site on how to do it for v5.1.

I find that Protel filenames isn’t necessary these days, but it doesn’t hurt.

Other manufacturers will also have help files on their websites with instructions.

What retiredffeline said.

An obvious candidate for switching to Lubuntu/Kubuntu/Mint. But that’s not an issue for here.

Thank You, Retiredfeline! I will check it out.
