How to deal with whitespaces in OS X along filepaths when certain UNIX programs dislike it

I am trying to include a command in a TeX file to a bibliography file that I am storing centrally.

However, when including the filepath, like

/Foldername with whitespace/ANOTHER folder name with whitespace/nowsinfldrname/bibo.bib

my Unix-based typesetting system complains. Is there a way to rectify that other than renaming my folders?
