Archive Attribute

  Every file on an MS-DOS partition has several properties associated with
  it.  One of these properties is called the Archive Attribute.  When a file
  has just been created, this attribute is set to be ON.  Also, if a file is
  altered, the attribute is set.  After a file has been backed-up by a
  program which uses this attribute, the attribute is switched off.  By
  making use of the archive attribute you may make certain that you get all
  files that are new or changed.  You save time by not backing up files you
  have previously archived.  This process is called an Incremental Backup.


  File Attributes

  Every file on an MS-DOS partition has several properties associated with
  it.  These attributes are: archive(a), hidden(h), read-only(r), and
  system(s).  The archive attribute is explained under the -i option.  The
  Hidden attribute prevents MS-DOS from displaying the file in a directory
  listing.  Files that have this attribute are normally ignored by PKZIP.
  The read-only attribute prevents a file from being changed or deleted.
  When a file has this attribute you cannot delete the file or change it's
  contents.  The system attribute signifies a file that is a system file.
  System files are used by MS-DOS and are treated as Hidden files.  Please
  see your DOS manual for additional information.


  Volume Label

  Every drive that can be accessed on your computer is referred to as a
  VOLUME.  This includes not only your hard disk but also floppy disks, and
  may include other storage devices such as CD ROM drives or large capacity
  removable drives such as those manufactured by SyQuest or Iomega.  Each of
  these drives may have a VOLUME LABEL.  This is a text string which
  identifies it.  This is particularly useful on removable media, such as
  floppy disks.  Each floppy may have a label which is meaningful to you, or
  to a piece of software.  For further information on VOLUME LABELS please
  refer to your DOS manual.
