How To Create Subfolder Using Cordova

I'm using Cordova and I tried to create a folder to the root of my SD card on a device. I used the following code for create the folder and add a file 'login.txt' inside it: window

Solution 1:

window.resolveLocalFileSystemURL(
        cordova.file.externalDataDirectory,
        function(entry) {
          entry.getDirectory(
            "myNewDirectory",
            { create: true, exclusive: false },
            function(result) {
              alert(JSON.stringify(result));
            },
            onError
          );
        }
      );

i'm using cordova create a folder to the Android/data//files success.

Solution 2:

var type = window.PERSISTENT;
   var size = 5*1024*1024;

   window.requestFileSystem(type, 0, successCallback, errorCallback);
   functionsuccessCallback(fs) {
       var dir=fs.root;
       alert('root   -'+dir.fullPath);// O/P:-root   -/
      dir.getDirectory('Albums', {create: true}, function(dirEntry) {
          alert('Albums Path:'+dirEntry.fullPath);// O/P:-Allbums Path: /Albums/
         dirEntry.getDirectory('Images',{create:true},function(subDir){
                              alert('Hello');
                              alert('SubDirPath='+subDir.fullPath);//output:-SubDirPath=/Albums/Images/
             //subDir.getFile('Log.txt',{create: true, exclusive: false}, function(fileEntry) {

        //writeFile(fileEntry, null, isAppend);
                 //alert('File Path'+fileEntry.fullPath);

    }, onErrorCallback);

         },errorCallback);
          dirEntry.getDirectory('Audio',{create:true},function(subDir){
                              alert('Hello');
                              alert('SubDirPath='+subDir.fullPath);//output:-SubDirPath=/Albums/Audio/
         },errorCallback);
      }, errorCallback);
   }
        functionerrorCallback(error) {
      alert("ERROR: " + error.code)
   }

This code helps to create folders and sub-folders in root. /Albums is the main folder. /Albums/Images/ and /Albums/Audio/ are the sub-folders(Images and Audio)
