[mark_e_h]

Is there a way using Calibre to select a group of books, and having Calibre show how much space they would take if downloaded to my Kindle??

thnx,

You will need to use a custom column:

program:

sizes = formats_sizes();

ifempty(
	select(sizes, 'AZW3'),
	select(sizes, 'MOBI')
);

This will return the size of the book in bytes, preferring AZW3 over MOBI just like the device driver.

You will need to add up the sizes manually, as custom columns are not aware of the metadata for other books.


Or for Kilobytes:

program:

sizes = formats_sizes();

final_size = ifempty(
	select(sizes, 'AZW3'),
	select(sizes, 'MOBI')
);

kilobytes = list_item(
	divide(final_size, '1024'),
	'0',
	'.'
);

@mark_e_h - if it's a lot of books you could create a CSV catalogue that includes the custom column, then read the CSV into a spreadsheet and get it to sum the column.
