How to backup DRM music from phone memory to PC

[joypaw]

Hi Experts,

I have recently installed Windows 10 insider preview on my lumia 830. Now I want to recover it back to 8.1;
But before that I want to backup my Copyrighted Music files that i have downloaded from Mix Radio and various Online sources.

The problem I cannot copy those files manually from windows explorer;
If I recover the OS now, memory will be erased and I will loose my musis collection

Any help is appreciated;

Thanks!
Joypaw!

The working principal of AOMEI OneKey Recovery is similar with Lenovo OneKey Recovery. But it is more convenient and easy for people, especially for common user to operate. The importance of backup needn’t be explained too much to every users of computer. Recovery partition is the great way to backup your system. If you have created a recovery partition that was made by AOMEI OneKey Recovery, you can click “recover” button. If computer can’t be started, press A key and computer will be recover to the state you made the latest system backup. Practice is the only law to judge theory. You also can create windows 8 recovery partition with AOMEI OneKey.
