Prospective employer accessing fbevents.js on my personal PC [closed]

I applied for a telecommuting job. The prospective employer said they needed to see if my personal PC was sufficient (RAM, available space, etc.). In order for them to do this, I had to copy an address into a pop-up window and select start. This process left a folder on my desktop and I saw one of the files was fbevents.js.

  1. Did they need this file to access my files
  2. Did they access this file from my PC and if so what might the purpose be?
