As you've seen from these illustrations, web page results and PDF results use file names derived from the date of the match.  A match held on August 2, 2004 would yield results names 2004-08-02.htm

What happens if you hold two (or more) separate matches on one day?

In that case, the software will put a letter after the date., i.e. 2004-08-02A.htm

When you are creating the second (or third, or whatever) match, the New Match Wizard will inform you of the letter it will be using:

 

 

That letter will appear on the list of matches.  It cannot be modified.  This shot shows a real example where I used the Classifier Extraction Wizard to copy the Classifier stages from a large match into a separate Classifier match so they could be scored and uploaded to the IDPA website.
