The files with the .sis extension are primarily categorized under the head of the Operating System Installer files. These are another type of files that should never be tampered with – not unless you want to crash the system! They are most commonly and extensively used by the Symbian system, created by the Symbian Company itself. The acronym sis stands for the Software Installation Script. Basically; it is just like an archive for the Symbian OS files. This is not an application file and thus, should not be mistaken with one. This type of installation file contains all the data which is necessary for the complete installation of a particular program package which is being run under the Symbian OS.
The actual application files which are used with the .sis files are the files in the .app format. They are actually added by the .sis files to that device in which the application is being installed. The Symbian command line tool which is used to create the SIS .sis files is the &qout;makesis&qout; command. This program also comes with the ‘createsis&qout; application program which may be used by the program developers while making applications for the Symbian system.
Who uses this type of file format?
Though the SIS .sis is mostly used by the Symbian system in the Nokia mobile devices, it is also used by other devices like Ericsson and Motorola phones. Generally, the Symbian S60 phone theme installation is the one which is created using these files. The creation of a .sis file can be done in many different ways. The most basic process of doing this is by creating a package definition file with the .pkg extension. The file with this extension contains the important information regarding the vendor, package name and the files included in the package.
Another way to create these file may be by using the Carbide.c++ IDE which can automatically build the .sis files for defining and creating the installation package. The different programs which can open the .sis files are Nokia Suite, Nokia PC Suite, UnSIS, Easy SIS Creator, Palm OS Emulator and SIS contents. The other applications which are compatible with this file type are Sisma by Digital Confidence, SiSoftware Sandra (a type of professional business script) by SiSoftware and the Student Information System Data File by Enray Consulting Inc.

- If you don’t have the program installed then you need to try searching for “SIS wiki”, “how to open SIS file” in the search engine.

File extensions are used by Windows operating system to specify what kind of information is stored in the file. Every file in Windows OS needs to have file extension and file extensions are used by Windows to determine which application it should use to open the file. Every application installed on Windows OS places information about which extensions it could open into the Windows registry and Windows uses this information to determine which application it should launch when user double-clicks on the file. If application which can open SIS file is not installed, then Windows will show ‘Windows can’t open SIS file’ message and buttons to either select an application on the computer which can open the file or to search the web for the application which can open SIS file.
