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.
