There are at issue two things here. In your initial post, you said . Lightroom Stores all of the work that you do on images (including the folder location) in the Lightroom Catalog file. This is why the link that I referenced earlier is so important —

The import process is not involved when moving your Lightroom data to a new computer.
The second issue is unrelated to moving your Lightroom files to a new computer. Normally folders are created in the import process or in the Folder panel . The only way to get the path to your image files into the database that is the Lightroom Catalog file is to use the import process or to create a folder in the Lightroom Folder panel . If you do not import directly from the camera card, and your image files are already in folders created by Windows Explorer or some other app (FastStone) then you still need the import proceed and it "ADD" function to catalog the image files and the path to those files.
The simplest workflow to get images recognized in Lightroom is to use a Cardreader and read the files from the card using the Lightroom Import process. This uses the Lightroom Import COPY process which copies the image files from the camera card to a destination of your choosing in the Import Destination panel. In the Import Destination panel, you can either let Lightroom create the destination folders for you using one of over a dozen 'date named' folder schemes or you can create manually your desired subfolder in the Destination panel. Note in this workflow, the Import Dialog can replace the extra work that you are doing with FastStone.
There has never been any difficulty copying photos onto Windows 10. Anything that you may have read is false information. If you insert your camera card into a card reader, Windows will recognize that card of images and want to copy them automatically into the Pictures folder and open the Windows Photo app. If you are using Lightroom Classic as your image manager, you will want to stop Windows from doing the automatic image copy and even remove the process from Windows start up so than it does not interfere. If you have Lightroom running at the time you insert the camera card into the card reader, Lightroom will automatically invoke the Import dialog.
There appears to be a lot of misunderstanding about how Lightroom works. You could probably benefit from the free eBook download that Victoria has created for people just like you
