How do I save changes made in the metadata of epub?

[webipsum]

Doubt Calibre:
How do I save changes made in the metadata of epub?
Because: I change the metadata in "Edit metadata", but does not change the epub file.
Grateful.

If you change metadata in the GUI it is not written to the epub file, but only stored in the database.

If you use any of the functions to send or save the epub outside the calibre library, then the metadata is written to the epub file. The same if you do any conversion or polish on the epub.

This behavior is intentional. It means that calibre can be used to store the original epub without ever modifying it. But when you send the epub to device, save it to disk or convert to other formats, then the copy is updated. Also it makes it faster to update metadata.

@webipsum - Polish does EPUB and AZW3, the optional Modify plugin can also do it for EPUB's only.

There's a new feature 'Embed Metadata' - it will embed metadata into formats EPUB, AZW3, and other formats eg PDF, RTF etc. Its 'simpler' to use than Polish or Modify because its single purpose, and its a bit faster. You may have to add it to your tool/menu bars. It doesn't have a keyboard shortcut, I gave it Ctrl/E.

Solved! 'Embed Metadata'.
Thank you BetterRed.

Please.
Still about metadata:
When I add a book in Calibre that has accents in the title, eg: "Associação". Calibre changes the filename to "Associacao".
How to configure Calibre to put in the file name, the same the contents of the Title - Author?
Tks.

But you do not want to have Calibre always updating the metadata when you send or save the eBook because it does a conversion and does mess with some of your code and that means when there is no metadata update, you still get the conversion. Check in the options to turn off this metadata update on a save or send so this won't happen. Use polish as then you can update only the eBooks you want updated and not all of them.

Tks.

Pure ASCII file names are OS safe
but when Save To Disk, there is a preference (is default) to convert non-english characters to English

It worked, but Calibre puts the title sort field rather than the title field, so the file name: "Um Navio - Author," appears as "Navio, Um - Author".
Tips?
Tks.

There is a Tweak that may help
Save_Template_title_series_sorting

If you us 'library_order', you get the {title_sort} as you have seen

No it doesn't. During a Save to disk or send to device, calibre does NOT do a conversion. Calibre only updates the metadata and replaces the cover image if it can find it. It doesn't make any other changes to the book. The update that calibre does during the send/save is less intrusive than Polish books.

Default: {author_sort}/{title}/{title} - {authors} don't work.
Example: "The Good" save "Good, The".

@webisum Check Preferences->Tweaks->Save_Template_title_series_sorting

Control how title and series names are formatted when saving to disk/sending to device.

The behaviour depends on the field being processed. If processing title, then if this tweak is set to 'library_order', the title will be replaced with title_sort. If it is set to 'strictly_alphabetic', then the title will not be changed.

If processing series, then if set to 'library_order', articles such as 'The' and 'An' will be moved to the end. If set to 'strictly_alphabetic', the series will be sent without change.

For example, if the tweak is set to library_order, "The Lord of the Rings" will become "Lord of the Rings, The". If the tweak is set to strictly_alphabetic, it would remain "The Lord of the Rings".

Note that the formatter function raw_field will return the base value for title and series regardless of the setting of this tweak.

The default value is 'library_order', try changing it 'strictly_alphabetic' - see screen shot

BTW if you're Brazilian - commiserations
