File TypeStuffIt X Archive
File format categories include Binary, Text, XML, and Zip. The format of this file type has not been determined.
A SITX file is a compressed file that uses the Stuffit X archive format created by Smith Micro StuffIt 7.0 or later. The StuffIt X format features Smith Micro's exclusive ATOM compression technology and offers up to 20% more compression than standard Stuffit (.SIT) archives.
SITX supports long-filenames, preservation of UNIX (ie: OS X) and Windows file permissions, and error correction, which fixes data transmission errors. It may also include 512-bit encryption for file security purposes. Version 9 and later allows 15-30% compression of JPEG images.
NOTE: StuffIt was previously developed by Allume Systems (formerly Aladdin Systems), but is now developed and distributed by Smith Micro.
