How to extract data from the iphone backup on the PC I have a huge amount of image files on my Whatsapp, which are locally stored on the iPhone. 

I do not see any way of moving these specific files from the iPhone to the PC, whereas of course from android this is as simple as connecting a USB cable between the two.

I have this iphone backup located in 
C:\Users\%user%\Apple\MobileSync\Backup\%some code%\
but the folder and file structure is seemingly encoded in a way only itunes/apple can decode.

Is there a way to extract an arbitrary file from the iphone?
Thank you.
Well, I´m not a pro-windows user here, but I do use some good old USB connection from my Iphone and my work computer using Autoplay


So, if you did save your images locally into your device, you should be able to get them from there !

Otherwise you should change the parameters of Whatsapp to save your image into your Photos and then try Autoplay.

As you said, it is as simple as connecting a USB cable between the two.
