ChangeXT - Version 1.0 How often have you needed to change the extension of a file? Maybe you needed to create a batch file or INI file from a text file, or an Active Server Page from an HTML file. ChangeXT will allow you to carry out this operation with the minimum of fuss. ChangeXT installs as an icon to your 'Send To' Menu. Now all you need to do is right click, choose ChangeXT and select or type the new extension.
