When I need to do that I just connect both computers to the same Wi-Fi or wired router (I usually go wired for this) then navigate to the directory that contains the neeed files and copy them over using File Manager.. And yes, Windows 10 still has file manager.. Should be in the quick menu (Left end of task/status bar) Manilla colored file folder.
NOTE: you may have to turn on file sharing for that folder
or you can copy it to the PUBLIC folder and copy it over to the new computer from there (into the target folder).
