Hello guys, I noticed that in lion is lacking the right click option "show package content", which is very needed to install some files... anyone knows how to solve it ?
Basically, a package is a folder that the OS doesn't treat like a folder. An application (always a package) is a folder with all the necessary resources contained inside the folder structure. However, the OS treats it as a single file so that when you double-click it, it launches the application (actually located a few levels deep in the folder structure of the package) instead of simply opening the package contents.
It's a neat way to do things, and is very helpful in keeping most applications as a single file, instead of pieces installed all over the place. Generally, you still get a few supporting files in the Preferences and Application Support folders in the Library, but for the most part it's all contained within the package.
