The FPSX format is associated with Symbian, the operating system used mainly in Nokia smartphones and other mobile devices. An FPSX file contains firmware data intended for a particular device or firmware release.
The file is part of the device-update and flashing process rather than a document or user application. On Microsoft Windows, Nokia Cooker can be used to work with compatible Nokia firmware packages. Firmware updates must match the target device and are not interchangeable between models.
Symbian is a legacy mobile operating system, so FPSX files are generally encountered in older device-maintenance and firmware-customisation workflows rather than in current software.
An FPSX file is not normally opened as a document. On a compatible Symbian device, use the device's supported firmware-update or flashing process and provide the file where that process requires it.
On Microsoft Windows, Nokia Cooker can be used to inspect or work with compatible Nokia firmware files. It should only be used with firmware intended for the matching device model.
There is no standard conversion from an FPSX firmware package to another file format. The file contains device firmware rather than ordinary user data, so it is normally used in its original form for updating or flashing a compatible Symbian device.
