Batch or script..plug-in?

Question

Hopefully somebody can help me with this question!
Will try to explain it as simple as possible;
I have a folder with for instance 60 files. In this folder are always three files that I want to combine in one PSD. The three files are bracketed pictures and normally you make an HDR with this. The thing is that I want them NOT to be combined but that the three files stay seperate. This can be done with File- Scripts-Load Files into Stack. So that’s not the difficult part but the difficult part is that I want to do the whole folder automatically.
In the end 20 PSD’s with all off them three seperate pictures of the bracketing. This is done with a batch or script as I an searching. Does anybody know a good plug-in for this or another program.
Thank you in advance.

Could you give this a try?
It assumes the files are in order.
// merge images in folder;
// 2014, use it at your own risk;
#target photoshop
// dialog for folder-selection;
var theFolder = Folder.selectDialog ("select folder");
if (theFolder) {
var theFiles = theFolder.getFiles(getSomeFiles);
// create the psd-options;
psdOpts = new PhotoshopSaveOptions();
psdOpts.embedColorProfile = true;
psdOpts.alphaChannels = false;
psdOpts.layers = true;
psdOpts.spotColors = true;
// the number of files to combine;
var theNumber = 3;
// work through files;
for (var m = 0; m < theFiles.length / theNumber; m++) {
          var thisNumber = m * theNumber;
          var theFile = app.open(File(theFiles[thisNumber]));
// place;
          for (var n = 1; n < theNumber; n++) {
                    thisNumber++;
                    if (File(theFiles[thisNumber]).exists == true) {placeFile (theFiles[thisNumber])}
// save the combined files;
          theFile.saveAs(new File (theFolder +"/"+ theFile.name.replace(/\.\D{3,4}$/i, "_comb.psd")), psdOpts);
          theFile.close(SaveOptions.DONOTSAVECHANGES)
////// get psds, tifs and jpgs from files //////
function getSomeFiles (theFile) {
    if (theFile.name.match(/\.(jpg|tif|psd|pdf|)$/i)) {
        return true
////// place file //////
function placeFile (thePath) {
