Robert,
In Library 5 of this forum is a file called "ARCHLP.EXE". This is an
executable program – you can just download it and run it as is. It will
provide you with a good tutorial on how to use the various archive programs
available. It is highly recommended.
Once you understand this tutorial, which among other things will teach
you how to determine exactly which archive programs you need, you will be
able to find the various archive/un-archive programs also in Library 5.
Hope this helps….
