I have searched a bite but cannot find a clear cut precise answer. I believe I'm not the only one looking for a clear definition.

  • What is a Wineprefix ?

  • What is it's function ?

  • What is a "clean" Wineprefix ?

Best Answer

  • WINEPREFIX is an envirnomental variable - https://help.ubuntu.com/community/EnvironmentVariables

    It sets where wine looks for it's configuration and files, well where it puts it's "C" drive.

    By default it is $HOME/.wine

    Some programs require very specific configurations and some people will use a specific prefix for different programs.

    See https://wiki.winehq.org/FAQ#Wineprefixes for details on how to do so and various options.
