Need networking advice

I am trying to transfer files from my laptop (Windows 10 x64, ver 1909) to my desktop (Win 10 x64 ver 20H2. I have a lot of options, but can't seem to get any to work:

1) Google Drive--I appear to have two Google Drives, one talking to my phone and laptop, the other to my desktop. How do I either merge these or get them both to talk to all?

2) Dropbox -- same problem

3) Ethernet, via my router. Can't seem to find simple instructions that apply to both Win versions

4) WiFi -- can't seem to find simple instructions that apply to both Win versions. Laptop won't always be on same desk as my desktop, and I have other PCs elsewhere, so this is probably best bet longterm.

Can someone please tell me where to find simple directions that will get this transfer running fast?

Share Files and Folders Over a Network in Windows 10

Two keys to making file sharing easier over the network:

1. Set Sharing permissions so that "everyone" has full access:



2. Turn off Password Protected Sharing:

If the computers are using the same Microsoft Account to sign in to Windows 10, you can just right-click on a folder you want to share and choose Give acces to > Specific people... > select the Microsoft Account in the list that appears > click on the Share button. That's it, you're done... it works even if the desktop is hooked up via ethernet cable and the laptop is using WiFi. This is exactly what I am doing right now, with two different laptops (one is on 1909, one is on 20H2).

As an aside, if both computers have a display that's turned on and is visible to you, then you can use a (free for personal use) program called Input Director that is super easy to set up, and that will let you use the keyboard and mouse on one computer to control the other one. It is similar to how Remote Desktop also shares the keyboard and mouse, but without sharing video output.

OR to keep it simple...just use a USB stick.
