What is a sisx file and how do I open a sisx file?
SISX is the extension for Symbian OS 9.1 or later device software installer files. It includes cell phones that support the Nokia S60 3rd Edition platform and devices that use the UIQ 3 platform. SISX files are similar to SIS files since both are created with the MakeSIS tool, and signed by the SignSIS utility.
