Library Restore?

Good Morning.

I recently did an update on Calibre, and noticed that all my books were gone. Somehow they were all moved into an archive folder. I moved them all back into the proper directory (Calibre Library), and assumed that Calibre would automatically recognize them, and re-populate the library. That did not happen. I have re added a couple books as a test, but they populate with the details (author, title etc) all messed up. I have spent many hours organizing all my books with proper data, and would not like to have to re-do all that work. Does anyone know a way to automatically get this fixed?

Looking into the Calibre Library directory, each book folder contains various versions of the book file (mobi, pdf, etc) possibly a cover jpg, and a metadata file.

Any help would be appreciated.

And if you want to re-import the books from a old calibre library folder into a new library, you can right click the add books button and choose (Add from directories, one book per directory)

Maybe you forgot to copy the file metadata.db and metadata_db_prefs_backup.json in the root of your library folder.
If you don't have these two files but all book sub directoriesin your library directory, you can try to make a library maintenance ->restore database. With this option the database will be rebuild from the saved metadata file metadata.opf of each single book directory. Take a look on calibre manual too. https://manual.calibre-ebook.com/faq...libre-is-blank

Edit: Kovid was faster...

Thanks Guys,

That got the books all back, and included a large quantity of the data. There are still things that need fixing, but the work level will now be much less.

I've never had a calibre update do anything to a library, let alone move it into an so-called 'archive folder'. Nor have I seen any reports of it happening to anyone else.

You might want to figure what moved and tampered with your library to prevent it happening again, I doubt it was calibre itself or the install. Which OS and which version are you using?

Calibre Library should never be run while the Library folder is Enabled for Sync. Always pause synch or bad things (changes fight ) can happen
