Solved File History issue

I use three main file backup systems, one of them being File History. All was well until I upgraded Win 10 to Win 11 a few days ago when File History appeared to have stopped working. Even running it manually it still wasn't backing up the latest versions of my files. After a bit of digging I discovered that the Win 11 upgrade had decided that my Library was now the OneDrive folder in my C:\Users account rather than the Documents folder in my D: drive where it used to be in Win 10. Is there a way to tell Win 11 File History where the library really is, as libraries don't seem to exist in Win 11 and I don't use OneDrive on a regular basis (and have since uninstalled it).

OK fixed, but if anyone else has this issue after upgrading 10 to 11, it is still possible to add a folder to a library in Explorer by right clicking the folder > Show More Options where there is a still a Include in library option. After that my File History is back to working normally.
