+ <para>The Win32 GetVolumeInformation and GetVolumeInformationByHandle APIs permit
+ applications to query volume attributes such as Case Preserving, Case Insensitive
+ lookups, support for hard links, support for reparse points, support for Unicode and
+ whether or not the volume is read only. The FILE_READ_ONLY_VOLUME flag when set permits
+ applications such as the Explorer Shell to disable the "Delete" and "Rename" options and
+ prevent copying files into the volume without issuing the request to the file system.
+ Unfortunately, the Windows 7 explorer shell has a bug when a drive letter is mapped to a
+ UNC path. If the mapped path refers to a read only volume, then all volumes accessible
+ via the drive letter are also treated as read only. This bug is fixed in Windows 8 and
+ Server 2012. To improve application compatibility the setting of the
+ FILE_READ_ONLY_VOLUME flag is disabled by default on Windows 7 and below and enabled on
+ Windows 8 and above.</para>
