What is a .SISX file?
A .SISX file is a type of software installer specifically designed for devices that run on Symbian OS version 9.1 or newer. This file format is commonly used to install applications on mobile phones that operate under the Symbian OS, particularly those that support the Nokia S60 3rd Edition platform or the UIQ 3 platform. Notably, many Nokia and Samsung smartphones are compatible with the Nokia S60 platform, while brands like Sony Ericsson and Motorola typically use the UIQ 3 platform.
To open a .SISX file, you can use several programs depending on your device and computer system. For instance, Nokia PC Suite is a popular choice for managing and installing .SISX files on Nokia phones from a Windows computer. Another useful tool is SISContents, which allows you to inspect and manage the contents of the .SISX file. Additionally, Deark is a program that can extract data from various file formats, including .SISX files.
It's important to note that .SISX files are an evolution of the older .SIS file format. While both are used for installing software on Symbian devices, .SISX files are specifically tailored for newer versions of the operating system (OS 9.1 and above) and offer enhanced security and capabilities. Developers create these files using tools like MakeSIS and SignSIS, which are part of the CreateSIS application suite, to package and sign the applications appropriately.
