File system: The operating system makes it possible to utilize space on a computer's disk drives by imposing a structured file system on disk storage. Each and every file system contains its own conventions for the manner in which the files are named, directories and folders are structured, and big files are splitted into smaller pieces, for example. It is not generally likely to transfer data directly from the file system of one operating system to that of a distinct operating system, since their conventions are probable to be incompatible.
