Screenshot 1 is my Documents folder where calibre always sits. The AGATHA CHRISTIE file seems to have been put there automatically when I loaded Calibre programme. Screenshot 6 is whats in it

Screenshots 2 & 3 are top and bottom end of the Calibre Library that was automatically in there when new laptop was built from the backup of the old

Screenshot 4 I tried by creating a new Folder called calibre Library New but when I put that as the location in " Use the previously existing library at the new location " -- I got screenshot 5

Got to be something stupid that Im not understanding.

I suspect the following is happening - in the restore process you have restored the configuration folder from the old computer which is referring to that AGATHA CHRISTIE library folder in your OneDrive - which may have got lost in the restore.

Curious - what sort of Restore was it, i.e. how was the backup created?

Try this -

1. start calibre,
2. go to Preferences->Miscellaneous and click the Open calibre configuration directory button, that will open the Configuration folder in File Explorer - it will be something like C:\Users\angus\Appdata\Roaming\calibre.
3. close calibre
4. in File Explorer go up to C:\Users\angus\Appdata\Roaming and rename the calibre directory to something like calibre_save.
5. start calibre (it will create a fresh configuration folder - silently)
6. now try the Create/Switch to the library folder with all your books (it may have picked it up if it is in C:\Users\angus\Documents\Calibre library

You would have lost all your global customisation and optional plugins, which you will have to redo - you could use the contents of the calibre_save as a guide, but I'd be cautious about copying things - especially bits of files. If you copy things (e.g the plugins sub-directory etc) make sure you do it while calibre is not running, and make sure you can undo any changes you make.

FWIW: when calibre is first installed (actually, at it's first run) it creates the following in %Appdata%\Documents if its not already there
