For example, the archive attribute shows that the file has changed since the last
full backup. The command line utilities described in this book can??™t access all of these attributes
directly. For example, even though some utilities can perform a task based on the offline attribute, none
of them can manipulate this attribute in any significant way. All of the inaccessible attributes appear
as part of NTFS. The following list describes the attributes that you can access using the command line
utilities.
A
The operating system sets this attribute whenever a file or directory experiences a change. The
attribute alerts backup applications to the need for creating a backup of the file under specific conditions.
However, you can also use the attribute to monitor the system for unexpected changes. For
example, unless you??™ve recently updated a particular Windows DLL, the archive attribute should
remain clear (unset). A change in the attribute status could indicate the activities of a cracker.
D
The directory attribute indicates that a file system entry is a directory, a container for other files
and directories. You can use the directory in a number of ways??”everything from mapping the
structure of your hard drive to locating hidden entities on the hard drive.
