SIS is an acronym that stands for Software Installation Script. It is an archive for Symbian OS, and not an application file, as sometimes believed; the real Symbian application is the .APP or .EXE file within it. By convention .sisx denotes a signed file.[1]

There are different ways how a SIS file can be created. The basic approach is to create a package definition file (.pkg) that contains information about the package like the vendor, package name and what files to include in the package. Then use the makesis and signsis utilities that processes the .pkg file and creates the actual SIS file.[2] Other alternatives are to use the Carbide.c++ IDE that automatically builds the SIS file as part of the build process or to graphically define and create the installation package using PackageForge.[3] The Windows utility SISContents is able to convert various file formats.
