Is metadata.db necessary to have in a folder for calibre to recognize it as a library? I installed the calibre app on another hard drive and tried alot of different ways to get calibre to recognise the books I had moved to this drive. The only success I had and it was not with that folder of books but an older folder that I had sent to this hard drive as a back up, was with a my kindle content folder, with a calibre library in it.
If I have metadata.db from a different calibre library can I copy it to another library without it changing any of the content in that library. If I hadn't had a sugarsync capacity I would have lost 50% of my books through my blind belief that my first or second attempt had worked.
If this is a stupid question I am sorry I am just baffled by my lack of success with what I thought would be an easy move.
