By default the finder on Mac OSX does not show the full file path of the current folder. This can make it hard to remember where a folder is, and can cause confusion when working with multiple folders with the same name.
Fortunately, there is a simple fix that will show the full file path in the finder’s title bar.
In the terminal type
defaults write com.apple.finder _FXShowPosixPathInTitle -bool true
And then to restart the finder
After that the folders full path will be displayed in the title of the finder.
