File system

From wikipedia

In computing, a file system or filesystem (often abbreviated to fs) is a method and data structure that the operating system uses to control how data is stored and retrieved. ⤴️

Directory structures may be flat (i.e. linear), or allow hierarchies where directories may contain subdirectories. ⤴️

Other bookkeeping information is typically associated with each file within a file system. The length of the data contained in a file may be stored as the number of blocks allocated for the file or as a byte count. The time that the file was last modified may be stored as the file’s timestamp. File systems might store the file creation time, the time it was last accessed, the time the file’s metadata was changed, or the time the file was last backed up. Other information can include the file’s device type (e.g. block, character, socket, subdirectory, etc.), its owner user ID and group ID, its access permissions and other file attributes (e.g. whether the file is read-only, executable, etc.). ⤴️

Some file systems allow for different data collections to be associated with one file name. These separate collections may be referred to as streams or forks. [⤴️
