Changes

So now Now we have files, folders and a system to navigate through those folders. We realise realised that some characters can and can't be used. We realise realised there are inconsistencies in approach due to historical inheritenceinheritance.

The next piece of the puzzle is giving people access to files. In the original FAT there was no place for file security. With the introduction of NTFS, files now in the index, could store security permissions for who could read, write, create and delete files. These permissions made the index a lot bigger but mean meant very fine control could be put on every file and folder. Management of these permissions is challenging.

Every file can have many different permsissions permissions which means that the modern operating system will attempt to group manage these permissions to as not to make your computer interaction experience a constant battle of adding and removing permissions. Windows provides an "inherit" capability that a new file in a directory will pick up the permissions of the folder that it is in. Folders can also inherit permissions from their parent folders and so on.
