How can I get a list of rated files in folders/subfolders?

Well, for some strange reason it's now working. So just ignore my previous post.

And thank you both.

OK. The script is working great, but not quite perfect and I'm having trouble understanding what is wrong. It's returing all the jpg files just fine. I also have psd and CR2 files that are rated. Those are not being added to the collections. I really only need it to filter by CR2 and psd files, though, and exclude jpg files. I just can't figure out why it won't return anything other than jpg file types.

One idea would be to put them into Collections.

as an example...

#target bridge
var folders =[];
var topLevel = app.document.presentationPath; 
folders = FindAllFolders(topLevel, folders);
folders.unshift(topLevel);
//Create 5 collection to put the files into
var FiveStars = app.createCollection("Five Stars");
var FourStars = app.createCollection("Four Stars");
var ThreeStars = app.createCollection("Three Stars");
var TwoStars = app.createCollection("Two Stars");
var OneStar = app.createCollection("One Star");
for(var a in folders){
var PictureFiles = Folder(folders).getFiles(/\.(jpg|jpe|jpeg|gif|eps|dng|bmp|tif|tiff|psd|crw|cr2|rle|dib|cin|dpx|ps|pcd|pict|vda|icb|vst|wbm|sct|pbm|flm|psb|exr|pcx|pdp|nef|dcr|dc2|erf|raf|orf|tga|mrw|mos|srf|pic|pct|pxr|pdd|pef|png|x3f|raw)$/i);
for(var p in PictureFiles){
var Rating =0;
var md = new Thumbnail(PictureFiles
).synchronousMetadata;
md.namespace = "http://ns.adobe.com/xap/1.0/" 
Rating = "'"+md.Rating+"'"; 
Rating =Rating.replace(/'/g,'');
switch(Number(Rating)){
    case 0 : break; /* No Rating */
    case 1 : app.addCollectionMember(OneStar,new Thumbnail(PictureFiles
)); break;
    case 2 : app.addCollectionMember(TwoStars,new Thumbnail(PictureFiles
)); break;
    case 3 : app.addCollectionMember(ThreeStars,new Thumbnail(PictureFiles
)); break;
    case 4 : app.addCollectionMember(FourStars,new Thumbnail(PictureFiles
)); break;
    case 5 : app.addCollectionMember(FiveStars,new Thumbnail(PictureFiles
)); break;
    default : break;
    }
    }
}
function FindAllFolders( srcFolderStr, destArray) {
 var fileFolderArray = Folder( srcFolderStr ).getFiles();
 for ( var i = 0; i < fileFolderArray.length; i++ ) {
  var fileFoldObj = fileFolderArray;
  if ( fileFoldObj instanceof File ) {   
  } else {
         destArray.push( Folder(fileFoldObj) );
  FindAllFolders( fileFoldObj.toString(), destArray );
  }
 }
 return destArray;
}
