Cleaning System Cache
WebStorm caches a great number of files, therefore the system cache may become overloaded. Sometimes the caches will never be needed again, for example, if you work with frequent short-term projects.
- From the main menu, select .
- In the Invalidate Caches dialog, select the relevant action. You can invalidate the caches and restart the IDE, invalidate the caches without restarting the IDE, or just restart the IDE.
