Odd Restore file, Can I delete it?

Hi Iam new here. I've looked for this subject before but I haven't found anything on point.
So, I had to do a re-install of my OS windows 10. I started to do it with a recovery usb I made when I first got the laptop but it crashed about 30% into it. After that it wouldn't work at all so I got a factory install usb from the Manufacturer, Asus and used that. It also crashed when it tried to deploy drivercd. I rebooted anyway and got to the Windows screen with System Preparation running. I chose Out-of-the-Box selection and set up windows 10. I got everything running okay and all the diagnostic programs return no problems.
However, when I go into Disk Management it looks a bit odd. In addition to the usual recovery, system and boot partitions and drives, I have one named RESTORE. It's huge, 95gbs, the SSD is only 250gbs. Also it's nearly empty. The properties show 0 used bytes and 0 free bytes. When I try to run check disk on it nothing happens, check disk just doesn't run on it.
I suspect it's a recovery partition but why is it so large and so empty? Could it be a mirror image the ASUS usb tried to set up before it failed and just didn't complete?
After I got everything running the way I want it to, I made a recovery usb using windows 10. If I delete RESTORE can I recover if necessary using the Windows recovery usb, either by doing a complete re-install or just a repare?
Originally, the laptop came with Windows 7 and I upgraded 10 a long time ago, but the USB ASUS sent installed Windows 10 and I didn't need to upgrade.
The computer is ASUS K501UX.
