Creating and Deleting Files and Directories

Learning how to create and delete files and directories is a basic data management skill:

1. To create a file in the current directory, use the createFile() method of the File interface:

   var newFile = dir.createFile("newFilePath");

2. To create a directory within the file system, use the createDirectory() method.

   The directory (and any sub-directories defined in the method parameter) is created relative to the current directory where the operation is performed on.

   var newDir = dir.createDirectory("newDir");
   var anotherNewDir = dir.createDirectory("newDir1/subNewDir1");

3. To delete a file, use the deleteFile() method:

   for (var i = 0; i < files.length; i++) 
   {
      if (files[i].isDirectory == false)
      {
         documentsDir.deleteFile(files[i].fullPath, onSuccess);
      }
   

4. To delete a directory, use the deleteDirectory() method.

   The second parameter defines whether the deletion is performed recursively for the sub-directories as well. If the parameter is set to false, the directory is deleted only if it is empty.

      else
      {
         documentsDir.deleteDirectory(files[i].fullPath, false, onSuccess);
      }
   }
