Save downloaded metadata in book

[Mamaijee]

I have a lot of epubs on my hard drive which do not have metadata.

I added a epub into Calibre from my desktop hard drive and then downloaded the metadata for it from the web. After the download I could see the metadata in the "Book Details" in the main interface. But when I saved the epub back on to my hard drive and opened the book, the metadata did not show in the book.

How do I save the downloaded metadata in the epub?

Thank you

Use the Polish tool or the ModifyEpub plugin. Calibre stores a copy of the metadata in it's database and in the metadata.opf in the book directory. The metadata is normally written to the epub when you use send to device or save to disk.

Simply copying the epub using the OS tools will not do the metadata update. And a bad habit to get into. Treat the calibre library as a black box and do not use your OS tools to manipulate the files.

Thank you for your reply David.
I used the Polish Tool, I selected "Update Metadata in the book file", I saved the settings, but there was no metadata when I saved the book to disk. What am I missing? I have to admit that my skills at Calibre are very basic.
I searched for ModifyEpub plugin but was not able to locate that.
My apologies, once again for not follwing your instructions.
Best wishes

Did you click on OK after Save settings? The Save settings buttons saves your selected options for the next time you use Polish books, it does not make any changes to the books. The OK button should start the Polish books job and show a results screen afterwards.

As for ModifyEpub, click on the arrow beside calibre's Preference icon. On the drop down menu, select Get plugins to enhance calibre. Select All in the filter list of plugins and start typing modifyepub in the filter by name box. See the attached image.

If you are using calibre's built in save to disk functionality, as far as I am aware, the metadata should be updated in the created copy of the epub.

David!!!! It worked!!
Thank you ever so much for your patient detailed explanation.
Took a few miss trials with my poor Calibre skills but with perseverance I got there.
Many many thanks
