Completely exporting a WhatsApp chat, including media and voice messages

I have a chat with a lot of voice messages, pictures and chat messages that I would like to completely export to my laptop, so that I can listen to the voice messages, view the pictures and read the complete chat history. The 'email chat' option only exports a small portion of the text and voice messages and just 8-10 pictures. As for the 'back up chats' option - I don't know what to do with the created files - as far as I understood from googling, they are meant to be read by WhatsApp itself - not by you on a PC/Laptop. Thank you for any help! Update: Kind of a solution: Decoding the WhatsApp encrypted backups - [link](http://forum.xda-developers.com/android/apps-games/decrypting-whatsapp-crypt8-v2-12-38-t3083847)
