[Old Thread] metadata.opf ?

[cybmole]

i run the new library check utility & it reports metadata.opf as an invalid author.

sure enough there is a file with that name in the root calibre library folder

should I delete that file - I hesitate to mess with anything called metadata !

The root folder should only contain metadata.db, so the file is at least out of place. Did you do some manual copying inside the library? What does the metadata inside the metadata.opf look like (open in text editor)?

I too have a metadata.opf in the root of my library. The last time I just deleted it but your question intrigued me so I checked it out prior to deleting it. It turns out it was the last book I added to my library. I'm not sure why calibre stashed it there. Maybe I'll be able to develop a trend as I find these files.

Huh, you're right. I have one of those as well. It contains metadata of the last added book, as in your case. Maybe we should wait for Kovid or someone to explain that...

That file shouldn't be there. I have seen it, but I haven't yet taken the time to figure out why it appears. If it is the metadata of the last added book, then the problem could be that the backup thread is being asked to backup a book that isn't quite real yet.

You can safely delete the OPF file (not the DB file).

Some day I will look for why this happens.

NB that's a recently added book, but it's not the last one I added

Theory - if I added this via the "add all books in a folder" option, maybe my source folder contained 2 files - the book file & this one. Calibre would place it in root directory as it could not see any author or title metadata ?

Nice theory but it doesn't wash with my opf. I just dragged and dropped a epub file from a directory to the book list.

Like Chaley, I don't think this is a high priority problem. The first time I ran into it I deleted the file without much thought the next time I just chalked up to a glitch that I could live with.

Hmm. I have another one

It has the index_number of the last book added to the Library.
I drag and drop when I add, fixing Metadata as I go
I DID edit the tags (list) originally that came with the EPUB file (Baen)

[chaley]

My suspicion was correct. These files are created because the backup task is given a book that is only partially created. The code now ignores such books.

I want to thank all of you for all your questions and answers. It solved my question. I will delete the metadata.opf file.

If I agreed with you, then we'd both be wrong.

Since this thread is so old the info here does not apply to any current existing problem. I would like to know what you think this thread helped you solve?
