Find and open files in subfolders

Question

Hi
Simple request I know but I can't manage to find how to make fileArray = targetFolder.getFiles("*.indd"); to access *.indd files inside sub folders and perhaps in sub sub folders..
Can anyone share how to do this?
Thanks in advance, Ken

Here is an example -- this script gets all indesign documents from the selected folder including its subfolders and puts all them into a book.
var myFolder = Folder.selectDialog( "Select a folder with InDesign files" );
if ( myFolder != null ) {
     var myFiles = [];
     GetSubFolders(myFolder);
     if ( myFiles.length > 0 ) {
          var myBookFileName = myFolder + "/"+ myFolder.name + ".indb";
          myBookFile = new File( myBookFileName );
          if ( myBookFile.exists ) {
               if ( app.books.item(myFolder.displayName + ".indb") == null ) {
                    myBook = app.open( myBookFile );
          else {
                myBook = app.books.add( myBookFile );
                myBook.automaticPagination = false;
                for ( i=0; i < myFiles.length; i++ ) {
                    myBook.bookContents.add( myFiles[i] );
                myBook.save();
//=================================== FUNCTIONS =========================================
function GetSubFolders(theFolder) {
     var myFileList = theFolder.getFiles();
     for (var i = 0; i < myFileList.length; i++) {
          var myFile = myFileList[i];
          if (myFile instanceof Folder){
               GetSubFolders(myFile);
          else if (myFile instanceof File && myFile.name.match(/\.indd$/i)) {
               myFiles.push(myFile);
Hope this helps.
