Hi Everyone,
I have fixed the issue by uninstall the PC Tools program called Registry Mechanic. Registry Mechanic appears to have been "over stimulating" the Tracerpt.exe process. After uninstalling Registry Mechanic and rebooting I had to manually delete the PC Tools folder (C:\Program Files (x86)\Common Files\PC Tools). Doing this freed up about 100 Gigs, it seems that when the Registry Mechanic program is uninstalled the ridiculously huge, "whatever", file is not automatically deleted.
Thanks again for all of your help with this.
Kind Regards,
Davo
