he means a extras.rcrs file that isn't in a .dlta or .theme or .whatever bundle. i think a problem that would occur would be that you couldnt have more than two of such files, and that you woldnt have a clue what it is. what i do is just open up a .theme file and delete everything, put in the new extras.rcrs, and edit the plist(or am i thinking of .dlta?). then you have a bare extras.rcrs but in a nice named package.
