Where Does Qt Creator Store Settings and Kits?
Qt Creator QtProject settings folders on Windows, macOS and Linux for kits, sessions and plugins.
Last updated
Qt Creator stores kits, sessions, snippets and plugin settings in QtProject folders under the OS app-data locations. Projects stay wherever you created them.
Kits are the fragile part of migration. They embed toolchain paths, so identical setups transfer cleanly and different ones need kit repair.
Where Qt Creator stores this, by platform
%APPDATA%\QtProject
Holds QtCreator.ini, sessions and plugin data. Close the IDE before copying. Kits embed absolute toolchain paths.
~/Library/Application Support/QtProject
Same role. Use Go to Folder in Finder.
~/.config/QtProject
Same layout under XDG config plus QtProject data in local share. Confirm the live path in About > System Information when unsure.
Frequently asked questions
How do I migrate Qt Creator kits and settings?
Copy the QtProject folders to the same locations with Qt Creator closed. Kits reference compiler and Qt paths, so matching toolchains on the new machine avoids broken kit entries.
How do I reset Qt Creator settings?
Delete the QtCreator.ini (and related config) with the IDE closed. Sessions and plugin state reset; projects themselves are untouched.
