SIS File Extension
Have a problem opening a .SIS file? We collect information about file formats and can explain what SIS files are. Additionally we recommend software suitable for opening or converting such files.
What is the .SIS file type?
The SIS file extension stands for Software Installation Script. It is commonly assigned to files containing information for installation of applications on various mobile devices with the Symbian operating system.
The .sis file format was significantly updated with the release of Symbian OS 9.1. The new version is based on a Type, Length and Value scheme and includes additional security options. Information is typically stored in a compressed form to make .sis packages smaller and therefore quicker to download.
There are many Symbian-based smartphones and PDAs that have built-in support for the SIS file format, including such big-name brands as Nokia, Motorola, LG, Lenovo, Samsung, Panasonic, Sony-Ericsson, and Siemens.
If you want to open a SIS archive, you need to transfer it to a compatible mobile device and launch an automatic installation process. It is also possible to open .sis files on your home computer or laptop using Symbian emulators available for Windows and Mac platforms.
