This is very helpful - thanks to shawn as usual - I just need to remember it all so it becomes automatic - I have yet to work out (I am sure the information is in the thread) how to add or remove files so that they always do or do not remain on the device I am using) - mostly I want to access the stuff rather than keep it always assuming OneDrive will never go completely Kaput unless those who will come after me also go Kaput then none of this will matter.
Hello Andrew,

You can right click on the file to check or uncheck Always keep on this device like below for this.

Mark OneDrive Files as Always keep on this device in Windows 10
