In CP/M, DOS, Windows, and OS/2, the root directory is "drive:\", for example on modern systems, the root directory is usually "C:\". The directory separator is usually a "\", but many operating systems also internally recognize a "/". Physical and virtual drives are named by a drive letter, as opposed to being combined as one. [1]
Screenshot of a Microsoft Windows command prompt window showing a directory listing.. In computing, a directory is a file system cataloging structure that contains references to other computer files, and possibly other directories.
The CP/M operating system uses a flat file system, with a directory containing information on a maximum of 64 files—adequate when a floppy disk held only 128 KB. IBM PC DOS and MS-DOS 1.0 inherited the same structure. DOS 2.0, which supported hard disk drives, introduced a hierarchical file system. The hierarchical file system was used ...
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
The filesystem appears as one rooted tree of directories. [1] Instead of addressing separate volumes such as disk partitions, removable media, and network shares as separate trees (as done in DOS and Windows: each drive has a drive letter that denotes the root of its file system tree), such volumes can be mounted on a directory, causing the volume's file system tree to appear as that directory ...
View of the root directory in the OpenIndiana operating system. In a computer file system, and primarily used in the Unix and Unix-like operating systems, the root directory is the first or top-most directory in a hierarchy. [1] It can be likened to the trunk of a tree, as the starting point where all branches originate from.
The directory given to the operating system is called the mount point – it might, for example, be /media. The /media directory exists on many Unix systems (as specified in the Filesystem Hierarchy Standard ) and is intended specifically for use as a mount point for removable media such as CDs, DVDs, USB drives or floppy disks.
A home directory is a file system directory on a multi-user operating system containing files for a given user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD systems use /home/ username or /usr/home/ username and Windows systems since Windows Vista use \Users\ username .
