   True.  But it makes no difference for the what The OP provided as an example   
   to the involved filenames.

   Very likely true.

   I have not tried it yet, so I can't tell you.  I do know that I can switch   
   off the "natural" sorting - and have done so.   I could imagine that some   
   registry editing by the batchfile (and reverting it afterwards) will do the   
   same.   
      
   But again, I took my que from his posted example.  It will certainly work   
   for that.   
      
   But, if you do not like Batch to do the "heavy lifting" than you (and/or the   
   OP) could use one of the other script languages Windows offers, and which   
   has a lot more capabilities than Batch has.   
      
   In my case I used, for the exact same reason as the OP, VBScript.
