The first version of DOS had a filesystem that didn't support directories! :)

It will never catch on! :)

  We laugh but iOS didn’t really support “files and directories” until quite recently.

    iOS, being a Unix, has always supported files and directories in full. It wouldn’t be able to work otherwise.

      It doesn't matter, when they aren't surfaced that way to the user.

        That’s like saying ignition doesn’t matter for an internal combustion engine because it isn’t surfaced to the user.
        pjmlp 6y ago
        Indeed, that is why cars are changing to electric and for the user the driving experience is mostly unchanged.

        > ignition doesn’t matter for an internal combustion engine You said ‘indeed’ which makes it look like you are saying this is true? I think you may be confusing the ignition switch or key, with the ignition of fuel in the engine. The ignition of fuel is absolutely necessary for internal combustion engines, just as a full file system was always necessary for iOS.

        Except a car doesn't need a combustion engine to fullfil its purpose, electric engines don't have combustion. There is nothing on the iOS experience that requires a file system with POSIX semantics. In fact that isn't what app developers using directly, rather Objective-C and Swift abstractions of a file system.

This is true, and is why using it as an analogy doesn’t work. > There is nothing on the iOS experience that requires a file system with POSIX semantics. Nobody mentioned posix before now.

This is not true. iOS provides all levels of Unix file system access from posix and libc upwards. Many apps and libraries make use of lower level access than Swift and Obj-C apis. In addition, even those abstractions won’t work without a file system. They depend on concepts like files and directories. This is why iOS had to have one when it shipped, and why a car power train is not a valid analogy.

Last time I checked, UNIX and POSIX go hand in hand, no one is moving goalposts here. The existence of a file system has nothing to do with UNIX, unless you now mean only UNIX has filesystems. https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html https://developer.apple.com/library/archive/documentation/Fi...
