Helm stores cache, configuration, and data based on the following configuration order:





- If a HELM_*_HOME environment variable is set, it will be used

- Otherwise, on systems supporting the XDG base directory specification, the XDG variables will be used

- When no other location is set a default location will be used based on the operating system





By default, the default directories depend on the Operating System. The defaults are listed below:





| Operating System | Cache Path                | Configuration Path             | Data Path               |

|------------------|---------------------------|--------------------------------|-------------------------|

| Linux            | $HOME/.cache/helm         | $HOME/.config/helm             | $HOME/.local/share/helm |

| macOS            | $HOME/Library/Caches/helm | $HOME/Library/Preferences/helm | $HOME/Library/helm      |

| Windows          | %TEMP%\helm               | %APPDATA%\helm                 | %APPDATA%\helm          |
