Thank to you both.
Mike. Is this what you meant when you said that unzippings were built
into Explorer (it uses zipfldr.dll in system 32)?
Best wishes
Sp.
Yes - there is no separate "program" called but the code of perform the
unzip and zip processes is stored in a Dynamic Link Library (DLL) that an
application can call and execute. So Explorer uses this DLL to perform
certain tasks, just a it uses several other ones of the rest of its
functionality.
It is a fine line as to what you consider makes up a program but it's
usually considered to the be sum of the EXE (executable) and all the
associated DLLs that it calls
