I am new to programmg. I have two forms, one with a file listbox sand the other with a listbox. A user selects a number of files. Those files then are placed into the listbox. What I want to do is rename the files in a sequentila fashion. For exaple if the user chooses "hill" for afile name and the are 50 selected files, I want to rename them hill_00, hill_01, hill_02, etc.
