Solve : What is C:\bksystem and can I delete it ??

1.	Solve : What is C:\bksystem and can I delete it ??
Answer» Hi Following the last Windows 10 Update, Windows has used up nearly 50% of the available space on my SYSTEM HDD. I've RUN a "DiskClean" and got back some space but the biggest space grabber seems to be a folder CALLED C:\bksystem which is nearly as big as the Windows folder! According to Treesize it has 27% of space, with some 770 subfolders all starting BKxxx, each withva single FILE called index What is this space grabbing folder and can I delete it ? TIA Geoff
