Hello!

I recently got a Kobo reader (Libra Colour) and have been learning the ropes. Not sure what kinds of software to install / whether I want to bother with Plato or KOReader yet or not, but I have been encountering some problems.

How does the metadata syncing work? I have a lot of PDFs that didn't have appropriate metadata on them (missing/malformed titles/authors). I only noticed this after loading the PDFs up on the Kobo. I edited the PDF metadata, and moved them back to the Kobo, but the metadata didn't appear to sync. After removing the files and copying them back entirely, only some of the metadata synced - but I have a lot of entries with "Unknown Author" or the wrong title still! It seems almost entirely random whether the metadata updated (though it did for most).

I'm really curious about the details around this. How does the Kobo keep track of books? (presumably not by hashes. is it by filenames?) Is there any way to force an update of the metadata database, for an individual file or for all files, without using something like Calibre?

Thanks for any help.
