File attribute

From Wikipedia, the free encyclopedia

A file attribute is metadata that describes or is associated with a computer file. For example, an operating system often keeps track of date a file was created and last modified, as well as the file's size and extension (and what application to open it with). File permissions are also kept track of. The user may attach other attributes themselves, such as comments or color labels, as in Apple Computer's Mac OS X (version 10.3 or later).

In MS-DOS, OS/2 and Microsoft Windows the attrib command can be used to change and display file attributes.
