caefile systemA file system in OS dictates how the contents of a storage medium are stored and
organized.
• These storage media (such as secondary memory, external drives, etc) could be
computer secondary memory, flash memory, etc.
• The contents are either files or directories.
• Most of the time, a storage device has a number of partitions. Each of these partitions
is formatted with an empty filesystem for that device. A filesystem helps in separating
the data on the storage into comparatively smaller and simpler segments.
• These chunks are files and directories. The filesystem also provides for storing data
related to files, such as their name, extension, permissions, etc.

• Files are stored on a storage medium such as disk and do not vanish when a user

sharing of that file.
• Files may form arranged or complex structures according to the relationship
among them.

mechanism, data loss/corruption prevention, etc.(0)(1)(1)
