Fill Documents directory manually on Android device

I have the following code returning YES in both cases: 

File documents = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS);
Log.d("DOCUMENTS", documents.exists() ? "YES" : "NO");
File subdir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS) + "/bla");
subdir.mkdir();
Log.d("DOCUMENTS","SUBDIR EXISTS " + (subdir.exists() ? "YES" : "NO"));

So the Environment.DIRECTORY_DOCUMENTS seems to exist on my device. But how can I add files to it manually for example with the Android File Transfer tool? Where is this directory located on my files system? I can't find it. I can see folders like Music and DCIM but nothing like Documents. Thanks.

    It seems to be an known bug, that not all directories show up using MTP, the protocol the Android File Transfer actually uses. Rebooting the device worked for me.
