On the Internet, ebooks can often be found with a random title, and that’s inconvenient to store them. Therefore, such books should be renamed.

Use this format:

Block, Ned et al. (eds.) - The Nature of Consciousness_ Philosophical Debates - 1997

et al. (et alii - and others) is used to abridge the list of authors.
(eds.) is used to indicate the editors of the compilation.

Windows doesn’t allow to use a question mark, quotation marks, or a colon in the file name. Use underscores instead.

If you want to list to authors, abridge the first name to one letter:

Osterhammel J., Camiller P. - The Transformation of the World_ A Global History of the Nineteenth Century - 2014
