Answer 1

Apache FileUtils does this very simple and nicely..

include Apache commons io package add commons-io.jar

or

commons-io android gradle dependancy

 compile 'commons-io:commons-io:2.4'

Add this code

String sourcePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/TongueTwister/sourceFile.3gp";
        File source = new File(sourcePath);

        String destinationPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/TongueTwister/destFile.3gp";
        File destination = new File(destinationPath);
        try 
        {
            FileUtils.copyFile(source, destination);
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
        }
