# Full List of Extensions

dhtmlxScheduler includes a number of extensions which add extra functionality to the standard behavior. 

To use an extension, you should activate it with the help of the [plugins](api/method/plugins.md) method.

:::info
In v6.0, the extensions code files were removed from the **ext** folder of the scheduler's codebase and included into the *dhtmlxscheduler.js* file. 

If you use dhtmlxScheduler 5.3 and earlier versions, check the [migration article](migration.md#53---60).
