How to open .001 files

How to open .001 files: In the following simple solution, I will show you how to open files that use numbered extensions like .001, .002, .003, .004 etc. These files are "split" and contain separate components or parts of a program and need to be "joined" back together in order for the application to work. In many cases, these parts will end up creating an ISO or Bin file. In other cases, the parts will end up making a directory that houses an installation directory for the program, or the entire program in ready to run form.
