Custom CFG File Format Specification

---

General Info

The .cfg file is used to load settings from a plain text file. A .cfg file may reside anywhere on the hard disk. The only restriction is that the filename must end in .cfg. Rockbox theme files (for setting up a WPS etc.) also adhere to this format, and end in .cfg.

Default CFG Values

Rockbox employs special processing if a CFG file named "fixed.cfg" is present in the /.rockbox directory. At power-on, the settings from config.cfg are applied, and then any settings present in fixed.cfg override those already set. This behaviour is particularly useful for values that you may change frequently while you listen, but that you'd like to revert to a fixed starting point between use.

Limiting the volume of the player on startup is a typical example; if you add:

        volume: -30

or your chosen value to fixed.cfg, this will ensure the the volume is always reset to a safe and comfortable level whenever the player is powered-on.
