The Mac OSX built-in GUI for navigating directories and files is Finder.app. I use it just about anytime I need to drag a file on my machine into Slack, Discord, Google Drive, or wherever else has a file drop zone.
Sometimes certain directories can be hard to navigate to because they are
deeply nested or because Mac hides them by default. The ~/Library directory
is a great example of the latter.
I can use the open command from the terminal to open a Finder window right in
that directory.
$ cd ~/Library
$ open .I first navigated there and then I ran open . which means open the current
directory. For directories, open defaults to using Finder.app.
I could have also run open with the target directory name instead of
navigating there first.
$ open ~/LibrarySee man open for more details.
