Android How to remove file from MediaStore.Files.FileColumns._ID

I can get external sd card file data from the

 MediaStore.Files.FileColumns._ID, and MediaStore.Files.FileColumns.DATA.

And I can use below code get the image thumbnails photo.

 MediaStore.Video.Thumbnails.getThumbnail(context
                        .getApplicationContext().getContentResolver(), item.getMediaId(),
                MediaStore.Images.Thumbnails.MINI_KIND, null);

Now I can get the media data full path.

Using below code to delete file.

  File file = new File(String.valueOf(path));
  if( file.exists() ) {
  boolean delted = file.delete();

  Log.i(TAG, "delted:/ :" + delted + "path:" + String.valueOf(path));
 // log show: false/ /storage/sdcard0/DCIM/100ANDRO/DSC_0012.jpg

              }

I found the file was not removed the path file.

I want to remove the file(real path photo and thumbnails phptp) from the path or ID.

How can I remove the file from get ID or path, and where my code problems?
