How can I automate opening all of my GRF files and export them to vector PDF?

This article contains a sample script for opening all GRF files in a directory and exporting each to a vector PDF file.

To run this script:

1. Copy the script below, or click here to download the BAS file: open and export.bas.
2. In a Windows Explorer window, navigate to C:\Program Files\Golden Software\Grapher 12\Scripter.
3. Double click on Scripter.exe to launch Scripter.
4. Press Ctrl+A to select all of the existing lines then press Delete.
5. If you copied this script, press Ctrl+V to paste it into Scripter. If you downloaded it, click File | Open, select the BAS file from your downloads directory, and click Open.
6. Click Script | Run to run the script.
