CC not writing updated metadata to file?

[KingJ]

I'm not sure if i'm making a mistake here or if there's an issue with CC, but when I edit a book's metadata in Calibre and then update the device metadata, the updated metadata doesn't appear to be written down to the file. Here's what i'm doing;

1. Edit an existing book's metadata in Calibre
2. Connect Calibre Companion to Calibre as a Wireless Device, opting to Sync
3. Manually trigging "Update cached metadata on this device" from Calibre

However, after doing this Moon+ Reader didn't recognise that the metadata has changed. Thinking it could be an issue with Moon+ Reader, I copied the EPUB back off the device and checked the OEBPS\package.opf file. This still had the old metadata in it despite having updated it in Calibre and forcing a metadata refresh on the device.

In Calibre Companion itself the metadata is correct, but it looks like the file itself that Calibre Companion is managing on my device wasn't updated.

To work around this, I need to tell Calibre to remove the book from the device and then re-send it.

Is there a better way that I can push updated metadata from Calibre?

I'm currently using Version 5.3.5.2 (381) with Calibre 3.7.

Many thanks

The metadata refresh only changes the metadata stored in calibre companion not the ebooks to do what you want you will need to first use polish to update the metadata in the books in calibre then connect calibre companion using wireless device sync new books option so that the books are sent again to calibre companion.

As you found out when you connect to calibre as a wireless device, calibre updates CC with the proper metadata. Since CC is meant to be the library manager which you use to open books in whichever reader you choose there is no reason any file needs to be updated. I use Moon+ Reader as my reader too and never have any reason to wonder if the metadata in the epub was accurate. I never actually use Moon+ Reader to navigate my books or open them.

You have discovered the only work around to accomplish what you want.

Are there any potential downsides to running the Polish operation? I tried it on a few books and it seemed to do the trick - the files were updated and CC then synced them with the new metadata. The only downside I can see is that I need to remember to run a Polish after updating the metadata.

I hadn't thought to use CC as the selector and Moon+ Reader as just a reader, but now that you mention it CC seems very much set up to act as a selector. I prefer having it all in one app but this could also be a potential option.

There's just one thing to keep in mind, if you change the metadata affecting the file name (for example, you correct the title of the book and when you re-send a book to the device the title is part off the name of the file) you'll either have two files (although in CC you'll only see one) or the old file would be deleted when sending the new one (Chaley can confirm what's the actual behaviour, I can't remember what it was).
If you had already began to read the book in MoonReader, you'll either see both books, or the old book (with its reading position, bookmarks and anotations) will be lost as MoonReader will treat the new file as a new book.

If the version of Android you run supports widgets you might want to check out CCs widgets, it makes reopening recently read books a snap. Never have to actually open CC or Moon+ Reader to resume reading your book.

It just changes the metadata of your calibre stored books. Personally I think it is better to update the files using polish as if you ever loose your calibre database because of corruption etc. You will loose most of the changes and have to restart when you re add the books.
