    Abstract: The concept of Čech fuzzy soft closure space (ČF-scs for short) is very recently defined and its basic properties  are  introduced  by  Majeed.  In  this  study,  we  continue  the  study  of  ČF-scs.  We  show  that every ČF-scs gives a parameterized family of Čech fuzzy closure spaces (ČF-fcss, for short). Furthermore, some properties of fuzzy soft neighborhood of a fuzzy soft point are introduced. Finally, the notion of fuzzy soft exterior (respectively, boundary) in ČF-scs is introduced and its basic properties are discussed, supported by counter examples.
