The Populous Renamer was a small application that TedTycoon wrote in mid 2003 using VB6. It allowed the user to swap the filenames of two Populous map files quickly. The program allowed you to choose whether to include the dat, hdr or ver file when it exchanged the two filenames. This application was made for TedTycoon so he could quickly swap two files in one operation so that he could test levels. The application was released through sending it to players but not published on his website.
