Why are these large mrbak files being generated on my C drive and filling most of the space?
I use Macrium Reflect to backup images and files to my D drive.
Because these unwanted files are being generated on my C drive they are also (over) filling my D drive.
I can regain a huge amount of space on both drives by deleting these files.
