VOSTRO 7510 - EFI directory in ESP partition filling up with dell.xx directories (prevents Windows updates)

Hi,

I had my Vostro 7510 for a while, still running Windows 10 Pro, and recently, I noticed that it was failing when it was trying to do Windows Updates.

I finally figured out what was causing the problem... the ESP partition had 0 bytes left.

I was able to fix the problem by moving partitions around and increasing the size of the ESP partition from 200 to 700 MB, so now I am trying to understand why the ESP partition got full in the first place, and I found that the "EFI" directory in the ESP partition has a bunch (like 30 of them) of "dell.xx" directories ("dell.00" through "dell.29" at this time).

What could be causing all of those dell.xx files to be created, and ALSO, can I delete some of the older ones to prevent the ESP partition from getting full again and the Windows updates failing?

Thanks,

Jim

EDIT:  Here's a screenshot of what the EFI directory in the ESP partition looks like now.  From testing, it looks like one new dell.xxx directory gets added every time I go to the Dell Support site and log in.
