I've tried doing some searching online and no one seems to be able to give an answer. I enabled File History on my new computer last night backing up to an external hard drive. This morning I checked to see if it was complete and under the Data folder in the File History back up there are two folders, 'C' and '$OF'. The C folder contains the majority of backed up files...but after sifting through the $OF folder I found it contains a lot (as in thousands) of additional personal files from my machine. These files have been renamed with a sequential number and timestamp and placed into sequentially numbered folders. I spot checked the files and found that it appears the files that have been placed into $OF are not in the C folder.
So the obvious question is why? What does the $OF folder represent? My hope is that File History is still in the process of fully backing these up and over time, they will eventually get placed into the C folder with their proper name. I plan to monitor through the day if there are any significant changes to this folder. But my bigger concern is that there was an error of sorts copying these files over and that the backup will remain in this condition...which is obviously an issue as if I needed one of these files I'd have to sift through thousands of files to find what I want.
Does anyone have an understanding of what exactly the $OF folder is and why it exists?
