The file is associated with Sony Ericsson mobile phone firmware and the SETool service utility. SETool uses the file when flashing or updating firmware on compatible handsets.
An SSW file contains firmware data intended for a particular phone model or firmware variant. It is a binary update image rather than a document or media file, and it normally forms part of the firmware files required by the flashing process.
SETool was used on Windows computers with Sony Ericsson phones.
An SSW file is not meant to be opened as a document. Load it in SETool on a Windows computer as part of the firmware flashing procedure for a compatible Sony Ericsson phone.
Use only firmware intended for the specific handset model and follow the tool's requirements, because flashing incompatible firmware can prevent the phone from starting.
SSW firmware files are not normally converted to another format. They contain device-specific binary firmware data and should be used in SETool in their supplied form.
