Vagon Streams allows you to run multiple files and scripts (.bat, Powershell, etc.) before, or after running the application itself. With this feature, it's possible to create custom flows like authenticating the application, resetting the application cache, transferring the user data to another platform or storage service for persistent storage, and more.
### How to Run Scripts & Executables for Streams
1. Choose the script or the executable file you would like to run.
2. Choose when you want to run via Run Schedule: **Before App Starts** or **After App Starts**
3. Choose the running trigger via Frequency: **Once for Each Stream Machine** or **On Every Visitor Session**
4. **Add New File / Script,** and so on.
You can add a new file or script rule anytime you want, and delete previously set ones.
