You are going to have to be careful doing the sort, however, because a simple string comparison won't work for numbers of differing lengths. One way would be to define a function that extracts the numeric components from a filename and produces a three-element tuple or list. Then pass this function to sort() as the "key" argument. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://del.icio.us/steve.holden Recent Ramblings http://holdenweb.blogspot.com -- http://mail.python.org/mailman/listinfo/python-list
