I have a Nokia Lumia 525 running Windows Phone 8.1. I want to access an audio clip received through WhatsApp. How can I access the file to copy it to another location?
Unfortunately it is not possible at this time per the information on the WhatsApp FAQ.
Currently it is possible to receive/send audio clips on Whatsapp. If the audio clip is an uploaded file (such as mp3 song) then it will be saved in SDcard/Phone -> Pictures -> Whatsapp. You can also find it in Music player. The name of the file usually starts with "AUD" followed by date and time.
Any recordings made from the Whatsapp will be saved in SDcard/Phone -> Pictures -> Whatsapp -> PTT
However the saved file will be in .ptt format which WP8.1 does not play by default.
My current version of Whatsapp is v2.12.300.0. This feature is available for quite some time.
