Can someone please explain what on earth this folder is in my WIN10 root and if I can delete it? I received a new pc (Surface Book) and after updating it I tried to SHRINK the single very large disk to allow me to reinstall my Insider partition but it would not shrink as much as I would have liked and I think part of the reason was this enormous 45GB folder of multiple entries around about 3MB over a 5 day period.

Can I safely delete the folder? I am concerned that it might be some disk temperature logging data which might be useful if I have a suspect drive which may need replacement... but I have no idea what it is but I am sure it was not on my previous pc which just died.
Any advice would be welcome. The naming of the individual files is like.. 3bd00e89-4117-4268-8405-587d943d214d
Thanks peter
