Mac OS X 10.3 Panther has a handy function on the finder's contextual menu for "archiving" a file/folder. It creates a zip file with macbinary data for storing the resource fork. It's very fast, and considerably better then stuffit archives. Stuffit Expander supports macbinary zip files... but not the format that panther outputs. Thanks to this tip on MacOSXHints, I've made an applescript droplet which uses the command line program Ditto to create MacBinary zip files which Expander CAN use.
