I downloaded "Mac OS 9.2.1 Update.smi" however the file arrived as a data fork only file. changing type to "APPL" and creator to "oneb" (which are the the codes for smi files) did not work. opening the file via expander or shrink wrap or disk copy did not work

a .sit version of the file did work just fine, but I would like to know what am I doing wrong with the smi files (or other executables for that matter)?
