On my external hardisk there are two folders inside a folder called "Sys". When I try to navigate to "Sys" using Finder (using "go to folder" option), I only see one folder inside "Sys".
When I use terminal to navigate to "Sys" folder and execute the command
ls -ltr I can see both the folders and can also
cd into them.
I also did:
defaults write com.apple.finder AppleShowAllFiles TRUE killall Finder
But the second folder is still not visible in Finder, and I also cannot navigate to it using Finder.

Installation is the invisible one.
