# About Plug-ins

Desk provides the capability to cooperate with other applications through plug-ins. Desk allows you to call up and execute many functions not provided with Desk itself by using the plug-ins.
Some plug-ins are provided by default in the in the [Useful Features (Ver. 9)] and [Task Steps] tabs on the Desk's task toolbar. You can use these plug-ins by adding them to the toolbar or task toolbar. Or you can modify the settings of the existing plug-ins.
