What is the mime type for .QFS files or how to write to SD card without mentioning mimeType

Question

I need to write a file of type .QFS to android external SD card. I need mime type to use documentFile.createFile(mimeType, File name) command to create file.

Can anyone please help me with either mimeType or is there any other way to create a file in android version 5.0 and above in external sd card without using the DocumentFile.createFile command.

This blog says - getExternalFilesDirs() and getExternalCacheDirs() will return directories that we can use on “real” external storage.

Add this in your activity for requesting runtime permission:

if (ActivityCompat.checkSelfPermission(YourActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
        requestPermissions(new String[]{ Manifest.permission.WRITE_EXTERNAL_STORAGE},
                REQUEST_FOR_STORAGE);//REQUEST_FOR_STORAGE=1111
    } else {
//Do your stuff here
            }
...

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {

if(requestCode == REQUEST_FOR_STORAGE){

   //Do your stuff here
  }
 }

Or may be by removing and resetting the sdcard write permission in the Android manifest file.
