thanks!You can do this in your file manager. I use ZArchiver.
1. Download the file, then go to your downloads once it's finished. Click on the file and click "Extract..."
2. Go to your Device Memory/Internal Storage

3. Press the button to extract the file.
You should be able to see the file in your internal storage. If ever a screen pops up asking for permission to replace files, just click "Replace all", then you're done:D
