IT - File System Components

Directory

A directory (also called a folder) is a container in a volume that holds files or other directories. It is used to logically sort and organize data to keep related files grouped together. Most operating systems use a hierarchical filing structure

File

A file is a one-dimensional stream of bits treated as a logical unit. They are the most basic component that a file system uses to organize raw bits of data on the storage device itself. The file name is made up of the directory path plus the file name. An extension can also be added to the file name to identify the file type and the program used to create, view, and modify the file.

Partition

A partition is a logical division of of a storage device associated with a hard disk drive -Multiple partitions can be assigned to a single drive -A separate drive letter represents each partition -assigning the boot system to a different partition than application and data files can help many computers run more smoothly and minimize damage in a system crash -Some OSs cannot run on a large partition. Creating a large partition for your operating system can help it run properly

Volume

A volume is a single accessible storage area within a file system. A volume can encompass a single partition or span across multiple partitions depending on how it is configured and what operating system you are using. Volumes are identified by drive letters.
