A little bit close
If "keep original format" is chosen in Settings, BD uses Word libraries to process some files. But not always, depending on the input file structure. For example, txt, pdf, and fb2 input files are always processed with the own BD converters.
However if somebody does not want to install MS Word, it is enough to check "re-format completely", and the files will be converted with the inner BD converters. But the initial formatting will be completely reconsidered. Sometimes it is better than with Word, sometimes worse...
