KCF File – What is .kcf file and how to open it?

KCF File Format

A KCF file is a Sony Ericsson HID Keypad Configuration file. It contains a list of key mappings that define how the physical keys on a Sony Ericsson mobile phone are mapped to different keys on a standard keyboard. This allows users to customize the way their phone’s keys function, making it easier to input text or use certain applications.

KCF files are typically created using Sony Ericsson’s PC Suite software, which allows users to connect their phone to a computer and configure various settings. The file format is a simple text-based format that consists of a series of lines, each of which defines a key mapping. The file format is as follows:


Keycode=<value> Key=<value>


For example, the following line defines the mapping of the physical key with the keycode “1” to the key “A” on the keyboard:


Keycode=1 Key=A
