{Who would want to do that?} I don't think anyone wants to hide file extensions on purpose. But, it's the default setting for Windows... so, I suppose it's Microsoft who "wants to do that". Yes, it's all part of their "protect the user" thinking... the same thinking that sets the "Hide system files" option to 'checked' and the same thinking that shows a "Are you sure you want to look at these files" message when you click on your 'Windows' folder (in Explorer)... well, gee, since I clicked on the folder, YES, I want to look at those files. Now, shut up with the stupid messages and show me the files.
