In this paper, we investigate more properties of the notion of co-F-closed topologies which was introduced by Abo Khadra and Nasef [1]. Several results which have appeared in [5] are expanded and improved. Also, we introduce a new concept of almost co-F-closed topologies of a given topological space and give a new class of functions, namely, almost F-continuous functions which properly contains the class of almost F-continuous functions (Chae et al., [5]). Finally, we show that the concept of almost F-continuity can be considered naturally from the point of view of change of topology.
