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
