Jpeg dtc compression info

Question

Hi
I have small but painful problem regarding jpeg format data info, i have a bunch of images and i would like to find out which ones are in progressive compression mode, so i can save them in baseline, i assume it's about 5% of all the images i have, and going through all of them 'save as optimized' is not a solution, if i make action for save as and close, it will take that action on all of the images in specified folder. 
Is there any way PS or Bridge can determine jpeg compression format in more convenient way? or any other software for that matter..

This will write the results for a selected folder to the desktop....
#target photoshop
main();
function main(){
var inputFolder= Folder.selectDialog("Select a folder of JPGs to process");
if(inputFolder == null) return;
var logfile = File(Folder.desktop+"/JPEG Listings.txt");
$.os.search(/windows/i)  != -1 ? logfile.lineFeed = 'windows'  : logfile.lineFeed = 'macintosh';
logfile.open("w", "TEXT", "????");
logfile.writeln("Processing " + decodeURI(inputFolder.fsName));
logfile.close();
var fileList = inputFolder.getFiles("*.jpg");
for( var a in fileList){
    getQuality(fileList[a]);
    alert  ("Please see results in " + decodeURI(inputFolder.fsName));
function getQuality(file){
var logfile = File(Folder.desktop+"/JPEG Listings.txt");
