Save paths and 'duplicated' books - is it specific to Kobo?

[ownedbycats]

For a FanFicFare and eReaders guide:

The default send-to-device save template is {author_sort}/{title} - {authors}.

If the title or author of a fanfic is changed, this results the book's save path changing and it being sent as a new file. However, if Calibre Preferences > Sending Book to Device > Metadata Management is set to 'Automatic management', it may also copy that title and author to the old copy on the device, resulting in 'duplicated' books.

I had this listed as a Kobo-specific issue but now not entirely sure. Is this limited to Kobo, or also happen on other devices as well?

Thanks.
