hi, i want to add a defination for my own file format.can you please tell me that how can i do that.

To add a definition for your own file format,click Web Options on the control panel home page.Then select the domain if you have more than one.After that
scroll down to find the MIME Type option on the Web Service page and click the Add icon on its right.Then agree with the charges.Now on the page that appears, enter the extension for this file type.
