Reset Qt Creator settings

To reset all Qt Creator settings, remove the settings files that it creates:

  • QtCreator.db
  • QtCreator.ini
  • qtversion.xml
  • qtcreator

The location of the above files and directories depends on the platform:

  • On Linux and other Unix platforms, look in ~/.config/QtProject and ~/.local/share/data/QtProject/qtcreator.
  • On macOS, look in ~/.config/QtProject and ~/Library/Application Support/QtProject/Qt Creator.
  • On Windows, look in %appdata%\QtProject and %localappdata%\QtProject.

To check whether the settings are causing a problem before resetting them, start Qt Creator from the command line with options.

Override the default settings path

To override the default path where user settings are stored, enter:

 qtcreator -settingspath <path>

To override the default path from where user-independent settings are read (for example, those written by the installer), enter:

 qtcreator -installsettingspath <path>

Start Qt Creator with temporary clean settings

To use clean settings that are deleted when you quit Qt Creator, enter:

 qtcreator -tcs
