# About the Start Command Execution Plug-in

You can use the start command execution plug-in to register frequently used applications and commands as plug-ins. When an application is registered as a plug-in, you can run this plug-in in Desk to start the application.
Also, if the executable file (external command) accepts document files, you can select a document and pass its path name to the external command to start the application.
It is convenient to register applications that are frequently used with Desk.
