## Using PersistentStateComponent
The [`com.intellij.openapi.components.PersistentStateComponent`](upsource:///platform/core-api/src/com/intellij/openapi/components/PersistentStateComponent.java) interface gives you the most flexibility for defining the values to be persisted, their format and storage location. In order to use it, you should mark a service or a component as implementing the `PersistentStateComponent` interface, define the state class, and specify the storage location using the `@com.intellij.openapi.components.State` annotation.

Note that instances of extensions cannot persist their state by implementing `PersistentStateComponent`. If your extension needs to have persistent state, you need to define a separate service responsible for managing that state.
