What is a sidx file and how do I open a sidx file?

The SIDX file extension, developed by Smith Micro, is StuffIt Archive Index Files created by the software StuffIt Deluxe. This is a utility used for compression and decompression of files and is made up of a list of reference information about particular files and these are located in a separate file archive. The application enables its user to go through the contents of a specific archive without the hassle of processing or decompressing it first. It is important to know that SIDX files are incapable of storing the files they reference. It only stores the file content information in a separate archive. Smith Micro StuffIt Deluxe version 2011 for Mac operating system and Smith Micro StuffIt version 2010 for Windows operation system is the main program that can open SIDX file extensions.
