Before COVID I was always traveling. I many have a more robust system than you want, but I'll detail it more below. But in answer to your question, don't get overloaded by the concept of moving QBs around, it is very simple.
On you Desktop where your current file is now, Press F2. About 1/4 down on the left side of the box that pops up you'll see:
FILE INFORMATION
Location (Something like where mine is... C:\Data\QBData\yourcompany.QBW)
Make note of that location AND know you can move the location if it's in some complex location that will not be easy to get to in the future.
Go to that location and simply copy the YourCompany.QBW file to your USB drive.
Go to your Notebook and copy the YourCompany.QBW to where the QB file is on your Notebook and simply say YES when it asks to overwrite the file. Open QBs on the Notebook and the latest info should be there.
Reverse the process when you get home.
NOTE: It is on you to always make sure you copy the file over to the OTHER computer to make sure you're working with the latest file. It will mess you up big time if you don't!!!!!
If you want to Relocate where the file is on both or either of the computers, simply copy the latest version of your file to wherever you want it. You'll note above mine is in a Data\QBdata folder. It is that way on both machines. Open QBs and it's okay if it goes right into the file in the old location. Go to FILE then CLOSE COMPANY. In the No Company Open box, click on Open or restore an existing company. Follow the prompts to where you moved the file too. Open that version of your company.
Once it's open and working, REMOVE the old original file. Now whenever you open QBs it will go to this new location.
Now then, the info you may or may not care about.... I have all of my User Data in a "Data" Folder. This includes not just QBs but my Doc Folder, Downloads, Photos, etc., etc., etc. It also includes a folder for my Desktop "Desktop Folder" and my Notebook "Desktop Folder" so that those also exist on both machines. Each computer points to it's own Desktop Folder, but the other one is there in case I left something on my Office Desktop and need it when I'm traveling.
I then use a program called Beyond Compare to sync the two Data folders over my network. Beyond Compare only copies the folders that are different, so you don't spend the time copying the entire Data folder every time. The default on each machine is set up to copy to the other machine. So before I leave, I sync from my Office machine to my Notebook. When I get back BEFORE I do anything on the Office machine I sync back the other way. It takes some time to set up all the machines and Beyond Compare, but once it's done, getting set to go on a trip and knowing I have ALL my files with me is a breeze.
(There is also a free Microsoft SyncToy App that works pretty well, but I like Beyond Compare.)
