On the Mac, the files are inside your Documents folder as shown in the following screenshot:

As we can tell, this is where all the cool stuff is located. If we ever need to reinstall Manga Studio, this folder should be backed up as it contains all the settings for preferences, keyboard shortcuts, customized tools, and much more. Fortunately, we won't have to directly install files into these folders; Manga Studio will do that for us.

To make it easier to look thing up and refer to the manuals, we can create a folder, name it Manga Studio 5 manuals, and put the Installation Guide, Startup Guide, the Users' Manual files, and the text file that contains our registration number in there. This way all the important documents are in a good and safe place. I have a pair of pocket notebooks that contain app names and their serial numbers. The notebook is stored in a storage locker with other important archival materials. It's better to have a number of duplicates and not need them, than to need them and not have a copy.
