Saving a cast library to a cst file

["Roofy" <webforumsuser@xxxxxxxxxxxxxx>]

Hi there,
 Okay this is a little embarrassing. From previously owning Director 8.5 to now 
trying out Director MX 2004, I cannot seem to find how you save out a cast 
library. In Director 8.5 there was an option in the save as dialog box to 
switch between cst and dir. However, in Director MX 2004, I cannot seem to find 
it in the dialog box. Where did Adobe put this feature? When I did a search in 
the help file, all I got was the lingo command for saving out to cst, but that 
is not what I want. What I want is to copy a cast library from an old file and 
use it in my new project. Did Adobe remove the save as cst feature?
