Was doing some routine maintenance on my RDSH farm and noticed that one server has much less free space than the others. I looked at which folders were the culprit and found this one:
C:\Windows\ServiceProfiles\LocalService\AppData\Local
It was full of files like the following:
FontCache-S-1-5-21-30371924-1664817342-1491421105-149182.dat
These files take up 50+GB of space. My guess they're associated with user profiles.
Are they safe to delete? I don't want to delete an actively used file.
