My Phone's screen is broken and my pc doesn't recognize it

Okay so a few days ago my phone (Huawei P9 Lite) screen completely gave out, and I have important files I haven't backed up on there, so I tried to emulate the screen on my PC trough the usb cable and a program but I found out my PC doesn't read my phone at all trough the cable, are there any other solutions to a problem that seems impossible like this?
