Open SITX File
A SITX file extension is a compressed file that takes on the Stuffit X file format, the default format used by StuffIt 7.0 and later.
About Stuffit X
StuffIt is a family of computer software utilities for archiving and compressing files.
Stuffit X was originally produced for the Macintosh, but later versions were created for Microsoft Windows, Linux, and Sun Solaris.
StuffIt was previously developed by Allume Systems (formerly Aladdin Systems), but is now developed and distributed by Smith Micro.
SITX format and Stuffit X
The proprietary compression format used by the StuffIt utilities is also called StuffIt, with the extension SIT.
The SITX extension featured Smith Micro's exclusive ATOM compression dev technology and had up to 20% more compression than standard SIT Stuffit files.
The SITX format supports long file names, preservation of UNIX (ie, OS X) and Windows file permissions, and error correction, which corrects data transmission errors.
SITX File Security
The SITX file supports password protection using 512-bit RC4 encryption or other encryption methods such as AES, DES, and Blowfish.
