Anyone know what this is and what its so huge? It is currently taking up 246 gigs on my hard drive!
Cant find info on it anywhere
Just Delete it. Even if it is a previews folder that LR is using it will get recreated when you next start LR. Delete it with LR Closed.
No previews folder is needed to start LR. If there isn't one LR will create one when it starts.
I some times delete mine just to clear it up.
