'''SCRNCH''' is a file compression utility for DOS. It can do executable compression of [[DOS executable (.com)|.COM]] files, and can create self-extracting files. It was developed by Graeme W. McRae, and distributed as shareware.<br />
<br />
SCRNCHed files are [[DOS executable (.com)|.COM]] files. It's not clear if there's a good way to identify them as SCRNCHed.<br />
