I am NOT asking how to copy data between PCs - I'm asking about PC-linq or an equivalent. I still have a PC-Linq 'bridging - cross-over' cable that used to allow data transfer between 98E and XP in an effective and user-friendly way. I would like to use it between Win10 PCs. There is a 2018 post on the web https://answers.informer.com/162205/is-pc-linq-really-working-with-windows-10 that claims it still works for Win10, provided it is installed and run As Administrator, and that the Compatibility Mode is set (for WinXP). I have done that and when it failed, I ran the Troubleshooter which came back with 'Mdi is incompatible'. Knowing that PCs often tell diagnostic lies, I figure that the software could be inadequate or any number of other gremlins could be causing the failure. I already know about work-arounds - the easiest being to use a USB-stick - and ethernet-wise, I KNOW that Team Viewer also works. After a great deal of effort, I've had NO success with networking through ethernet cable, so spare me reminders about THAT option. The only modern version of PC-Linq I could find, from USBGear https://www.usbgear.com/windows-10-data-transfer-cable.html, has user comments at https://www.amazon.com/dp/B004GIGNVC which range from EXCELLENT to ABYSMAL. I'm really NOT after work-arounds, or asking how to transfer data between PCs, but in finding out if anybody-out-there can reproduce the success in getting PC-Linq to work with Win10 which was claimed by the post I quoted. I want to cast a wide net by asking for help in forums.
