File Format
Name DOS/Windows file attributes
Ontology

The DOS/Windows file attributes are a set of standard one-bit attributes for a file or directory. The original form was a one-byte field associated with FAT, but it has been extended and updated over time. Some archiving and filesystem formats have a way to store (some subset of) these attributes.

[edit] Table of attributes

Some of the one-letter identifiers used by the ATTRIB command are included in this table.
