The goal of this program is to: 1) Rename the file to include the PONum from inside the file 2) Pretty-Print (format) the XML inside the file 3) Preserve (keep) the original date/time of the file

NOTE: Use $maxFiles=1 when testing, then set maxFiles=999999 when done testing.

NOTE: If you want to re-run this multiple times on same folder (or from the task scheduler), you don’t need to not re-process files that have already been processed. I usually do this by putting a double underscore in the name, then skipping past any files that have the double underscore in them.
