Deleting messages in whatsapp I had lot of private and group conversations over an year through whatsapp, but all of a sudden the space it takes seems to be  on a high.I was able to delete private messages by long pressing the person's file and deleted the entire conversation but when I long press the group chats I didnt quite find an option to delete the conversation all at once.Is there any way to delete private messages all at once rather than doing them individually.
Go to WhatsApp settings> Chat Settings> Delete All conversations
