Hi,

I move sometimes my Calibre Library using Google Drive, and I'm facing the problem with the books ids between parenthesis all the time.

So I wrote a small program to fix your library.

On the computer with the library without the ids in the folders name, open my program and indicate the directory of the calibre library, and click "Fix". It will add the correct ids to the folders name according to the data in the metadata.opf file of each books.

Only works under Windows at the time, requires .Net Framework 3.5 Client.

Hope this helps!
