I think there are several confusions taking place here.
1) Renaming a file doen't change its internal data structure. You have to start with a file of the correct format. .DDS texture files are quite different from .JPG image files.
2) In order to use Windows GUI interface to change a file's extension so that it agrees with the file's internal data type, you first have to change the properties of the desktop folders. You have to turn off the feature "hide extensions for known file types". This is one of the menu options when you open any desktop window. Under XP it's in the "Tools" menu, the item "Folder Options...", the tab "View". Unfortunately, I don't recall the details for making that change under W2K.
However, if you open a "command window", often mistakenly called a "DOS window", you can use the command "rename" to change the extension directly.
I hope this helps a little.
