WhatSwap

The WhatsSwap offers a quick and easy way to move your media files downloaded by WhatsApp to your external sdcard , saving you time and the internal memory of your device. In an easy way, the application checks from time to time, your WhatsApp media directory and copy all files ( photos, videos and audio) downloaded to your external sdcard . In addition, you can set whether or not to delete the copied files from source location.

IMPORTANT: This app only works on devices running old Android versions (up to 4.3), due to a restriction added on Android 4.4 preventing external sd card access.
