Running macOS 10.15.7 (Catalina). I am looking for folders which I can delete to free up some storage space. I see
/usr/local/Caskroom seems to contain installation files for some packages which, I guess, I must have installed via
brew cask or something.
Are the files under
/usr/local/Caskroom needed for some purpose after installation? If not, then I could delete them without interfering with the installed packages, yes?
