What is an .--- file?
The --- file extension is used probably by older versions of Windows and MS DOS operating systems. Temporary files may be created by computer programs for a variety of purposes; principally when a program cannot allocate enough memory for its tasks, when the program is working on data bigger than architecture's address space, or as a primitive form of inter-process communication. Used by various applications.
