What is folder? - Definition from WhatIs.com
Part of the Computing fundamentals glossary:

In the Windows , Macintosh , and some other operating system s, a folder is a named collection of related file s that can be retrieved, moved, and otherwise manipulated as one entity. The folder and file terms were chosen to be consistent with the metaphor that the user interface is a desktop . In some other operating systems, such as DOS , z/OS and most UNIX -based operating systems, the term directory is used rather than folder.
