Как сконвертировать несколько сотен .SVG в .AI и не свихнуться?

// file: convert_svg_to_ai.jsx

app.userInteractionLevel = UserInteractionLevel.DONTDISPLAYALERTS;

var inputDir = Folder.selectDialog("Input Dir?");
var outputDir = Folder.selectDialog("Output Dir?");
var files = inputDir.getFiles('*.svg');

var saveOpts = new IllustratorSaveOptions();
saveOpts.compressed = true;
saveOpts.embedICCProfile = true;
saveOpts.embedLinkedFiles = true;
saveOpts.pdfCompatible = true;

for (var f = 0; f < files.length; f++){
    var doc = app.open(files[f]);
    var newFile = new File(outputDir + '/' + doc.name);
    doc.saveAs(newFile, saveOpts);
    doc.close(SaveOptions.DONOTSAVECHANGES);
}

app.userInteractionLevel = UserInteractionLevel.DISPLAYALERTS;
