Hello! I have a bit of a situation which I'm hoping you can help with.
I recently lost my Calibre folder (all folders, all ebooks), although I still have the metadata (OPF) that Calibre displays. I also have a
separate folder containing the same books that Calibre used to have but not the same structure, no OPF.
So although the books appear in Calibre, I cannot 'use' them. For example double clicking it will bring up this error.
What I would like to do is to restore the files from my 'other' folders back into the Calibre folder structure so that I can restore my book collection
and preserve metadata.
What would be the best way to do this? I have roughly 300 books so I am trying to avoid doing this manually. I am familiar with scripting if necessary.
