What is the difference between a directory and a folder?

Question

Most people use the terms \"folder\" and \"directory\" interchangeably. From a programmer point of view, is there a difference, and if so, what is it? Does it depend on the OS,

Answer 1

• Directory is a file system concept. In a GUI the directory is represented as a Folder.
• Example 1: Unix systems, /usr/bin/ is usually referred to as a directory when viewed in a command line console, but if accessed through a graphical file manager, users may sometimes call it a folder.

Folder: The name folder represents an analogy to the file folder used in offices:

Analogy:

• A Folder is like a room.
• A Directory is like a hotel keeper who knows all the rooms.

If you want a specific folder, you use the directory. If you want a specific room you ask the hotel keeper. Source
