Calibre has its own directory for items that are in the library, along with its own database. When you add a PDF file to the library, it is saved in this directory and recorded in the database. At the same time, your original PDF file remains where it was. Now it is duplicated on your disk — delete it or keep it, as you prefer.
-
The function in Calibre is used when adding a PDF document to the library; it retrieves the Author-Title-... from the metadata of the added PDF document
OR extracts it from the file name and
records it in the Calibre database.
-
The function in the plugin works with a document that is already in the library. If you edit the metadata in library, it is automatically saved to the database, and this plugin also writes it directly
into the PDF file in the Calibre directory.
If you don't use the plugin but want to have the metadata directly in the PDF file, set it in "Save to Disk" and then save the file to your disk. This is not written into the PDF file in the Calibre directory!
