Opening SISX files

Did your computer fail to open a SISX file? We explain what SISX files are and recommend software that we know can open or convert your SISX files.

What is a SISX file?

Files that contain the .sisx file extension are installer files for mobile devices that use the later versions of the Symbian operating system. They are referred to as Symbian Series 3 installation packages.

The SISX files define the way the applications are installed on the Nokia phones that operate on the Symbain operating system. Prior to Symbian version OS 9.1, the installer files were saved as .sis files. Once Symbian OS 9.1 was released the files were saved with the .sisx extension. This file format makes it easier and more convenient to distribute and install applications onto the Symbian-operated device.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
