![]() There are different ways of organizing these files and storing data about them - “file systems.” The metaphor here is a paper filing system - the bits of data on a computer are called “files,” and they’re organized in a “file system” the way paper files might be organized in file cabinets. If your operating system doesn’t understand a file system, you may be able to install a file system driver that provides support - or you just can’t use that file system with that operating system. Your operating system needs to understand a file system so it can display its contents, open files, and save files to it. The file system also provides an index - a list of the files on the drive and where they’re located on the drive, so the operating system can see what’s on the drive in one place rather than combing through the entire drive to find a file. It also provides a way to store data about these files - for example, their filenames, permissions, and other attributes.
