Icons for files are kept track of in BNDL and FREF resources, which contain which ICN# goes with which file type. Most programs only keep the BNDL and FREF resources in the Application file itself and don't copy them into the data files (which is the right thing to do). If there is no file on the disk which contains the BNDL, FREF, and ICN# for a given file type (like if you put a Microsoft Word file on your disk without Microsoft Word itself on your disk), the icon will be the standard, blank, "I don't know what this is" icon. It's a little more involved than that, but simply, that's what's going on. What you should have pointed out is that simply copying over the BNDL/ FREF/ICN# combination may not be enough--the Finder renumbers. Simplest way to cure this is to copy the app to the disk, then delete it (unless you still want it around, of course :-). -- ============================================================================== | Francis Stracke | My opinions are my own.
