Someone will need to give you a small program that can do that.  I'm not 
going to,
because the language I write my utilities in won't be on your system and 
you'd
have to install and configure it, and understand what you were doing 
before you
could move on and actually use it.

But someone established elsewhere in the thread that VBS (I think it 
was) will run
on your system.  I know nothing about VBS but someone will tell you what 
to do.

Jan Stary has - again - pointed you at some code that would work on a 
Linux system
but not on Windows.  In essence what it does is

  - makes a list of all the files in (eg a 'left files' folder), whose 
names end in "wav"
  - then one at a time, work through that list, and:
      - work out the full name of the corresponding 'right' file
      - work out the full name of the corresponding stereo file
      - issue a sox command with all three names in it

As Jan pointed out, a simple loop like this isn't a terribly good idea; 
it's better if
there are some sanity checks in it as well - making sure that the 
derived 'right' file
actually exists before you try to use it, make sure that the result file 
doesn't exist,
stop if the sox command fails...   If it were my code I would probably 
also check that
the left & right files had the exact same size before they were used.
