Program Data is huge; something's wrong

c:\programdata\dell\saremediation\systemrepair\snapshots is huge and is creating hundreds of new files every day.

This folder contained files for 15 years ago!  This can't be right! 

Well over 1,400 .dll files were created just today

I'm trying to manage space on my drive and these files are taking, in total around 24 GBytes.
