Where Are CLion Settings Stored?
CLion stores settings in versioned JetBrains folders in home. Config holds user settings while system holds caches and logs.
Last updated
CLion uses a separate folder set for each major version. The config folder holds keymaps, color schemes and plugin settings. The system folder holds caches and local history.
Paths follow the standard JetBrains pattern. You can override them with idea.config.path and idea.system.path in custom properties. Old cache and log folders are pruned automatically after 180 days without use.

Frequently asked questions
What should I delete to clear CLion caches?
Delete the system folder for that CLion version while the IDE is closed. Leave the config folder intact to preserve settings. Restart to rebuild indices.
Where are CLion plugins?
User plugins are in the plugins subfolder of the versioned config folder. Use the IDE plugin manager for installs when possible to avoid version mismatch.
