最近项目中使用到很多资源需要使用swf格式，但是资源太多，就想到了jsfl，这个家伙太厉害了，有了他工作量就大大减少了，晒下代码分享给大家，写的比较乱，注释也不全，大家如果需要即时交流哦

fl.outputPanel.clear();

var resourcePath=fl.browseForFolderURL("请选择素材路径：");
var swfPath=fl.browseForFolderURL("请选择生成swf文件的路径：");

analyseFolder(resourcePath,"");

var childName = "";
var flag = false;
//递归处理每个文件夹
function analyseFolder(folderPath,libFolder)

if(libFolder == ""){
   childName = "";
}else{
