When I was teaching at a Tech. College in the early 1990s, one of the student exercises were implementing a simplified Kermit over a serial line between two PCs. The first part of the exercise was soldering a null modem cable. This was commonly known among the lecturers as The exercise that the students would remember, and come back to the lecturers to thank them for providing, many years later. The students learned a lot about communication, synchronization, debugging of distributed systems, ... Even though the setup was very simple, all the elements were there.
At that time, I also learned that the oil company of the Norwegian state (it has been renamed a few times; I think it was named Statoil back then) actually used Kermit for transferring data from their 'technical', VAX based systems, to their 'administrative', IBM mainframe based systems holding their huge databases. They had made several unsuccessful attempts at finding some protocol implementation for direct VAX to IBM communication, but both companies were famous for their 'Protocol xyz with a twist' policy, using that 'twist' as a wrench to force their customers into obedience. But both were willing to pass files to/from PCs (of their own DOS variants, of course), and both PCs were capable of running Kermit over a null modem cable. When I visited them with a group of students, they proudly showed us the two PCs, side by side on a small desk, running as "modems" between this huge IBM mainframe and this powerful top-range VAX, transferring data at 19.2 kbps 24/7.
Bottom line: Kermit may be an alternative. It has been used for such purposes by billion-dollar companies.

I used a product called LapLink long ago, with special blue or yellow cables, depending on serial or parallel.

Share a folder and use a network cable

Not an RJ45 connector on the MacBook Air. Not sure where to find its network cable.

Yay! This worked. Could transfer almost instantaneously. Thanks a lot.
How do I double-upvote this?

USB To Ethernet Adapter optional?

Perhaps a USB/RJ45 adapter?

I created a "subnet" and I connect to my headless mac mini via ethernet & vnc.
However, the setup also allows me to just connect directly & drop files on the mac mini like a file storage unit.
I wrote up how I set it up at: macbook pro - Is is possible to use remote desktop to a Mac via direct cable or wireless? - Ask Different[^]
This talks about the RDP but it also explains the settings that work to connect with ethernet. It should get you there.
good luck
the write-up has screen shots for both sides of the setup (windows & mac) so it should help.

USB jump drive?
You might need some sort of hub or cable to use as an adapter.

Make sure to use the parallel port adapter and not the serial port adapter! Guaranteed 8 times faster.

Which computer has a parallel adapter nowadays?
Several years ago, I dug up some old serial port equipment, for plugging it into my computer. I searched it all over, but couldn't find the serial port. The computer was a couple years old. I had owned it for more than two years without noticing that it didn't have an RS232 serial port! (Later, I discovered that the mainboard actually had a COM1 header, so I could have plugged in an old bracket with a 9-pin RS232 socket from one of my old, discarded PCs, but at that time I had found alternate solutions.)
To find a PC with a parallel port, I will have to visit the museum part of my old PC collection. They never ran anything but DOS.

Use a Zip Drive!

When you on wifi. Share a drive on the sending pc and from the other pc copy normally from the sending pc from the shared drive in your file explorer.

I assume you have a wireless network. On the computer that needs to share files, install python 3.
Open a command line promp in the folder with the files, and run this:
python -m http.server 8000
Your computer is now a file server, sharing all files in that folder.
Easiest way IMO and you can download everything with decent speed.

I use remote desktop and tick the filesharing option.
