ARCHOS box rock - Manual (Page 41)

Plugins are little programs that Rockbox can load and run. Plugins have the file
extension .rock. Most of them can be started from the main menu if you put them in
the /.rockbox/rocks directory. Press PLAY on them to start them.
Viewer plugins get started automatically by "playing" an associated file (i.e. text files,
chip8 games), or from the “Open with” option on the File menu.
The plugin loader
Only one plugin can be loaded at a time. Plugins run in the GUI thread and have
exclusive control over the user interface. This means you cannot switch back and forth
between a plugin and Rockbox. A plugin is loaded, ran and then exited, which returns
control to Rockbox. Music will carry on playing whilst plugins are being run.
