Preferences are settings which are persistent for every session of Siril, and which define your prefered choices for many of the tools.

Since version 1.2.0, they are accessible both from the user interface or programatically, by using set/get commands.

By default, the preference file is located at:

  • ~/.config/siril/config.ini (Linux)

  • %LOCALAPPADATA%sirilconfig.ini (Windows)

  • ~/Library/Application Support/ (MacOS)

If you wish to have multiple configuration files, you can choose which one to start from by opening a terminal and typing:

siril -i path/to/my_other_config.ini


Siril needs to be in your path to use siril as in the line above. Otherwise, use the full path to Siril binary.
