Save as PNGs.jsx
This sample gets files specified by the user from the
selected folder and batch processes them and saves them
as PNGs in the user desired destination with the same
file name.
// Main Code [Execution of script begins here]
// uncomment to suppress Illustrator warning dialogs
// app.userInteractionLevel = UserInteractionLevel.DONTDISPLAYALERTS;
var destFolder, sourceFolder, files, fileType, sourceDoc, targetFile;
// Select the source folder.

// If a valid folder is selected
