Lumia 950 XL :: Transferring Photos From Windows 10 PC To Device

I recently purchased the Lumia 950 XL and have had a pretty terrible experience transferring photos from my Windows 10 PC to the device.

With phone connected to PC via the included USB-c cable, I'm dragging and dropping my photo albums from my PC into the Pictures folder in the phone's local memory. However every so often, the transfer will hang on a specific photo. Sometimes it will hang for minutes at a time and I'll need to kill the process manually. Other times it will error out, saying "the device stopped working or was disconnected". Once either situation occurs, the phone's folders in Explorer become unresponsive (i.e. clicking through the phone's folders, refreshing the view, and ejecting the phone via the taskbar do not work), and I must physically unplug the phone and plug it back into the computer in order to be able to try again. The phone interface itself remains functioning and fully accessible while this is occurring.

Typically I can get a problem photo to work by opening it in Photoshop, making some small change (i.e. drawing a single pixel in it), and saving it. This seems to clear whatever error was in place, but only until I hit the next time this happens on subsequent photos. In some cases I've been able to add photos or full albums without issue - in others, every single photo in an album was problematic and could not be fixed by altering in Photoshop.

I've looked for issues in the photos themselves, but don't see anything that's telling me what they may have in common vs photos that do work - they open fine on the PC and don't appear to be corrupt. This never occurred previously with these same photos when transferring in the same fashion to my Lumia 1520 via a standard USB cable. I thought perhaps I had a faulty USB-c cable, but I tried with two spare cables and the same thing occurred. I also tried using different USB ports on my computer (both USB 2.0 and 3.0) and nothing changed. Rebooting the PC / phone doesn't work either. I've yet to test if this also happens with other file types, i.e. music.
