A fixed layout epub displays a fixed page and not the reflowable display from a normal epub. It's useful for kid's stories where you want the graphics and text to have fixed locations on the page and other books where fixed locations can be advantageous. The only fixed layout epub I have that actually makes sense is Harry Potter: A Journey Through a History of Magic from the British Library.

Where is the J: drive located? Is it a local drive, on a NAS or a cloud connection (OneDrive, GoogleDrive, etc.). If it is not a local drive, see I am getting errors with my calibre library on a networked drive/NAS? in the calibre FAQs.

Edit: In one of the html files, there is a path which is invalid (the \\JfONDAY' bit in the error message).
