DeSEA is a tool designed to remove "Self-Extracting" code (.sea) from compressed files. Compatible with Compact Pro, Disk Doubler and StuffIt (see below).

Excerpt from the Release Notes:

A disturbing trend has developed as of late. With the proliferation of multiple compression utilities, everyone has begun to create self-extracting archives (SEAs). While this is all-and-well, self-extracting archives add to the file sizes of files being transferred. While 10-20K for the self-extraction code isn’t much, it rapidly adds up over multiple transfers. In addition, the use of self-extraction features on small files can often cause the file to be larger than the original, uncompressed file.
DeSEA removes the self-extraction code from a self-extracting archive. DeSEA first saves any resources which are to be preserved, strips the resource fork, changes the type and creator of the file, renames it with the proper file suffix, and restores the saved resources. Since the compressed data is always stored in the data fork, no important data can ever be lost since the data fork is left completely intact. DeSEA can be run on a single file or on an entire folder of files. DeSEA is currently configured for the three most popular compression programs: Disk Doubler, Compact Pro, and StuffIt Classic/Deluxe and can be extended to support other formats (see below). DeSEA will also recursively search sub-directories if the option key is held down when dropping-and-dragging or when selecting a folder from standard file dialog in the application.

Architecture: 68k

System 6.0.x seems to have a problem with applications other than the Finder which change the Finder flags of an application. If a file which is being DeSEA’d under Multifinder (6.0.x) is currently displayed in an open window, its flags may not be set properly if the file is moved. It is therefore advisable under System 6.0.x to close the windows of files being DeSEA’d. System 7.0 doesn’t appear to display this obnoxious behavior.
