[Q] Not Sure Where to Post This topic

Ok, this is definitely a rather unusual question and may not even be able to be answered on this site (perhaps not even within show of the site - if so, my apologies).

The problem: I have a Dell Inspiron 15 laptop with urgent files. The screen is broke.

What resources I have: I have been using a HDMI cable to use my TV as a monitor, until I broke the cable. I have a second laptop (HP 15-1009wm J2V78UA#ABA) fully functional (does not have BT radio). I have T-Mobile HTC One M8 unlimited everything + hotspot. I also have a Cricket ZTE Sonata z740g (the digitizer is broke and I have to remotely control it over Wi-Fi with the M8).

How can I set up either phone or the HP as an extended display, at the very least (I can ctrl+a , alt+m, and use arrow keys to move the desktop files - where the urgent folder is - or even ctrl+a , ctrl+c [or x], ctrl+v. Anyway, I'm sure everyone here knows that. I want to know if anyone knows if this is possible to retrieve the files (with absolutely nothing pre-installed for remote management) without having to physically swap the drives - it's a pain in my arse, you know, proprietary issues. It can be done though, just trying to avoid it.
