Where in the filesystem are the dictionary files used in the native Mac Dictionary app located? In previous OSes, they were in Library/Dictionary. I don't see that directory in MacOS Big Sur.
More importantly, how could I effectively search for them? I tried searching my whole computer in the Finder for the keywords "dictionary" and "oxford english", and they didn't appear. Are the files hidden? Would there be a good terminal command to fuzzy keyword search all files including hidden ones? Or, would it be possible to see what files the Dictionary app uses by examining the app, somehow?
