### Hi Everyone!
Are you ready for another round? Let's dive in!
Here's the link to the video: [Watch now!](https://www.youtube.com/watch?v=TeZ-PdvNsss&t=1366s)
In this session, we'll wrap up our previous example and put into practice what we've learned.
*Key Takeaways:*
1. *Data Handling*:
- What seems like a massive amount of data to us is processed by a computer in the blink of an eye!
2. *TouchDesigner Helper Methods*:
- TouchDesigner provides several helper methods through the TDFunctions Python modules, courtesy of Derivative.
- You can find these helper methods in your TouchDesigner project directory:
```
/sys/TDModules
```
- Remember, TouchDesigner is largely built with TouchDesigner itself!
*Key Functions to Explore*:
- `TDF.getParInfo()`
- `TDF.ApplyParInfo()`
- `op().getChildren()`
With this simple yet powerful combo, you can save and recall parameters for every operator within a given directory.
As always, happy programming!
Best,
Simo
