More info

SEA files bring along their unpacker to sit or zip files, so that later Stuffit is no longer needed. Starting an SEA file starts the unpacking process. Some older SEA files created on Mac OS 9 or earlier may not be automatically unzipped on MAC OSX. In this case, it is recommended, for example, to install the StuffIt Expander and use it to open the SEA file.

Of course, under Windows, SEA files can not be started because they are not executable Windows files. However, you can use the Stuffit Expander (for Windows) to extract SEA files.
