### Where is the data directory?
If the `XDG_DATA_HOME` environment variable is set the data directory will be
`$XDG_DATA_HOME/code-server`. Otherwise the default is `~/.local/share/code-server`.
On Windows, it will be `%APPDATA%\Local\code-server\Data`.
`$XDG_DATA_HOME/code-server`. Otherwise:
1. Unix: `~/.local/share/code-server`
1. Windows: `%APPDATA%\Local\code-server\Data`
