= List of Supported Filesystems =

A file system is a logical way of storing data on a storage medium. It determines how files and directories are stored, retrieved, sorted, protected and recovered.

A simplified overview:

Most (all?) storage devices use '[[sectors]]' which are small addressable units of space on their medium that actually store the [[binary]] data that makes up a file. A file system logically "collects" one or more of these sectors into an addressable '[[block]]'. For example, a file system may create 2,048 [[byte]] blocks made up of four 512 bytes sectors on a hard drive's physical platter.

When a file system stores a file, it determines how many blocks will be needed to store the file, splits the file's data into the appropriate number of pieces and writes them to the various blocks and records in an index or table what blocks contain the parts of the file and in what order they were saved in. To later retrieve the file, the file system will consult it's index or table to get a list and order of the blocks that contain the appropriate data and then go and collect the contents of those blocks and rebuild the file.

So in summary; a file system is a piece of software that stores data on and retrieves data from a physical storage medium. How it does this, and what limits and features it has, depends on the particular file system in use.
