It's possibile to redirect WhatsApp media to the external sd card in order to save memory. The redirection will take place after one day. This delay allows the user to see the files properly when they are received, but after this period media are visible only on the gallery because on WhatsApp they are out of focus.
There is also a Filter to select files you need to move, for example Photo, Video, Audio or customised files.
✓ Redirect one Folder.
✓ Redirect one WhatsApp Media.
✓ Set a redirection Delay.
✓ Select a Filter for Photo, Video, Audio or costumised files.
✓ Manual Redirection.
✓ Sent WhatsApp media redirection.
✓ Delete automatically Sent Media of WhatsApp.
✓ Redirect multiple Folders.
✓ Redirect all WhatsApp Media.
✓ No Ads.
ATTENTION PLEASE FOR ANDROID KITKAT AND ABOVE
The App isn't compatible with Android 4.4 and above.
This is due to a changing of Google policy who doesn't allow to write to External SD Card.
