Application Data Directory
The application data directory, mostly referred to in this documentation as APPDATA (from the name of the environment variable that, on Windows, determines its position within the user home directory), is where all persistent data common to When, whenever, and whenever_tray is kept. Its actual location depends on the host platform:
~/.wheneveron Linux%APPDATA%\Wheneveron Windows~/Library/Application Support/.wheneveron Mac.
Logs and configuration files can be found in this directory.
When launching the resident wrapper, the following parameter can be specified on the command line:
-D/--dir-appdataPATH: specify the application data and configuration directory
However, it is recommended not to specify a custom APPDATA directory unless really needed, because by default both When and whenever_tray use this directory to locate the scheduler configuration file – that is, the one generated by When in configuration mode.
