I think this would probably work except I really need to know which ones 
are out of sequence as is, changing the filename would eliminate that 
capability and the missing files are the ones I need.  See, I'm 
receiving the files from a separate server and they are sent to me in 
this format.  I need to know which ones I /don't/ receive so I know 
which ones I need to have resent.  Make sense?
