%localappdata% being the file explorer shortcut but C:\Users\MYNAME\AppData\Local\Frontier Developments\Elite Dangerous\Options\Bindings
being the full dir path
just copy all the frontier folders located in the sub diretory over to the new pc for all your history visted stars ect to go over too
after you have run the launcher installer package from the drive you want the main bulk of files to goto (so move it from my downloads first)
If you cant see them you will need to enable(via the tickboxes) show hidden file and folders in the pc control panel file & folder options
to make them visable as they can be hidden as the op mentioned
see the bindings guide stuck at the top of this pc subforum for how to fully customise your bindings noting version 4.2 are for odyssey and version 3.0 is for legacy
