how do you sort and manage your ebooks? i've got like 100 gigs of unsorted ebooks, mostly epub, which random file naming conventions. i wish there was something like musicbrain picard, that automatically scans meta data of all files in a given directory and renames the books accordingly, following a uniform format.

any tips or suggestions before I embark upon this huge waste of time just to scratch an ocd itch. pardon the cringey op image.
