NTFS

New Technology File System

In plain language

The file system Windows uses to organise and store files on a drive, including who may open them.

The metaphor

Like the filing system in a records room that also notes which staff may open each drawer.

Going deeper

How it works

  • Stores each file with its permissions.
  • Recovers from crashes using a journal.
  • Supports large files and encryption options.
  • Shared folders on Windows use its permissions.
In practice
  • A shared folder restricts who can read it.
  • A drive is formatted for Windows.
  • A backup tool preserves file permissions.

A question owners ask

Why does it matter?

Its permissions decide who can open shared files, so reviewing them helps prevent oversharing.
