Recently I found out that there is a hidden folder .snapshot in \local that is keeping daily backup. Inside I see folders like 'AM.DAILY.01', 'PM.DAILY.01', ..... with almost the same content . when I try removing them it says that it's a read-only folder. It is using A LOT of storage and I don't know what to do.
I am not a sudoer by the way.

Thanks in advance
