Automatically Output Font List across multiple files?

With this I need to be able output these into a text file for compiling a list. I didn't see any way inside of Bridge to actually export the metadata, it ony seems to show it.

I was able to get the script setup and loaded as a jsx file (also swapped .eps for .ai)and it appears to at least fire off correctly inside of Illustrator. It's asking for a folder and it outputs a Font.info.txt file, however it's erroring out with the message "Unable to load the AdobeXMPScript Library!" and the text file is just left blank, so I'm assuming something in there isn't going through correctly.

This is the version I used:

#target illustrator

var inputFolder = Folder.selectDialog("Select a folder contains '*.ai' files ");

if (inputFolder) {

    var fileList = inputFolder.getFiles('*.ai'),

        fontsInfo = [];

    loadXMPLibrary();

    for (var i = 0; i < fileList.length; i++) {

        if (fileList instanceof File && fileList.hidden == false) {

            fontsInfo.push(getFontsInfo(fileList));

        }

    }

    unloadXMPLibrary();

}

var Loginfo = new File(inputFolder + '/Font.info.txt');

Loginfo.open('w', 'TEXT', '????');

var info = fontsInfo.join('\n\n');

Loginfo.write(info);

Loginfo.close();

if (/(Open Type|TrueType)/.test(info)) {

    alert('Open Type / TrueType font found, see log file for details!')

}

function getFontsInfo(file) {

    var arr = ['File: ' + decodeURI (file.name)],

        xmpFile, oXmp, fontNumber, i, path, fontname, fonttype, ns = 'http://ns.adobe.com/xap/1.0/t/pg/';

    xmpFile = new XMPFile(file.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ);

    oXmp = xmpFile.getXMP(); //Returns an XMPMeta object

    fontNumber = oXmp.countArrayItems(ns, 'xmpTPg:Fonts');

    xmpFile.closeFile(XMPConst.CLOSE_UPDATE_SAFELY);

    if (fontNumber) { // if there's at least 1 font, proceed

        for (i = 1; i <= fontNumber; i++) {

            path = XMPUtils.composeArrayItemPath(ns, 'xmpTPg:Fonts', i);

            fontname = oXmp.getStructField(ns, path, XMPConst.TYPE_FONT, 'fontName');

            fonttype = oXmp.getStructField(ns, path, XMPConst.TYPE_FONT, 'fontType');

            arr.push([i, '. ', fontname, '-', fonttype].join(''));

        }

    }

    return arr.join('\n');

}

function loadXMPLibrary() {

    if (!ExternalObject.AdobeXMPScript) {

        try {

            ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript');

        } catch (e) {

            alert('Unable to load the AdobeXMPScript library!');

            return false;

        }

    }

    return true;

}

function unloadXMPLibrary() {

    if (ExternalObject.AdobeXMPScript) {

        try {

            ExternalObject.AdobeXMPScript.unload();

            ExternalObject.AdobeXMPScript = undefined;

        } catch (e) {

            alert('Unable to unload the AdobeXMPScript library!');

        }

    }
