File Extension

Hope you can help.
I'm using Windows XP.
I have some data on a DVDR that is in ISO format,
The thing is it is really a gi file, so in order for me to access it I need to change the file extension to a gi file instead of an iso file, in order for me to burn it with Prassi.
Do I make sense ????
I just want to give this one file a gi extension in order for me to burn it.

Can You Help?

Thanks In Advance.

 

Try copying it to your hard drive, then clear the attributes, rename and burn. Or, use Nero and burn it from the *.iso format. HTH.
