   I don't think you can count on a file extension *always* being 3 
characters. Consider all those ".html" files out there, for instance. Therefore, it 
might be best to modify this code as follows:

  answer "Select a file"
  if it is empty then exit to top
  put it into tFilePath
  set the itemDelimiter to "." # i.e., period
  put the last item of tFilePath into tExtension

   You may get into trouble with files that don't actually *have* an 
extension... but then again, such files could yield problematic results with the 
*original* code, too, so I think the ability to handle 4-character extensions is a 
win, overall.
   Hope this helps...
