You can change your production's current script to a new file you've uploaded by doing any of the following:
- Clicking the ellipses next to the file in the Binder window and clicking "Set as Current Script".
- Checking the box next to the file's name and click the yellow "Set as Current Script" button in the bottom bar
- Opening the file and click the ellipses in the upper right hand corner
Once you've changed your current script, you can archive or delete any files you don't want to keep in the Binder.
