I mostly add books which originally are in zipped fb2 format (file_name.fb2.zip). Calibre opens, processes and places them into the library in the fb2 format (unzipped). Is it possible to place and keep books in the library in the original (zipped) format? I know that after adding books Calibre itself can convert them in zip format, but it is not a complete workaroun because the structure of zip files Calibre creates is different from the original one (not fb2.zip).
Thank you!
