File Extension SISX

The file extension SISX is associated with the Symbian operating system, which is an operating system used with Nokia and a number of other mobile devices. Symbian OS is one of the first user friendly operating systems for mobile phones and the platform is still widely used for Nokia mobile devices.

The file extension SISX is categorized as a miscellaneous file type which stores installation packages and archives that are used with the Symbian operating system. SISX files are used with the 9.1 version of Symbian OS or later which is installed with Nokia S60 or UIQ 3 platform. The S60 platform is used with Nokia and Samsung mobile devices where the UIQ 3 platform is installed in Motorola and Sony phones.

The file extension SISX is similar to the file extension SIS except SISX files are used with newer devices. SIS files are installation files which are used for devices that operate with Symbian OS on older devices. Both SIS and SISX files contain data which is separated into two parts. The first part of a SIS file contains metadata to describe the files which are to be installed on a mobile device. The second part of the file contains the actual data related to the file which is used for the installation process.

The two part process is created by the MakeSIS application and use a signature from the SignSIS utility. The two processes assume the name of makesis and signsis.
