Hi. I have an HTC Desire 610, and I installed whatsapp several weeks ago mainly to communicate with people in my family. I'd like to know how to back up the messages and other things in whatsapp (basically the crypt7 files) so that I can read them, if necessary, on my computer as well. I don't want to download any rogue apps to either my phone or my computer. I regularly do a phone backup and also regularly copy all the files from my phone to a special folder on my computer, but I can't read the crypt7 files. Thanks in advance for any help with this.
