<h1 class="topictitle1">Volume, directory, and file names</h1>
|
|
<div><p>The volume identifier for the primary volume descriptor can be
|
|
a maximum of 32 characters. The volume identifier must contain only alphabetic
|
|
characters (A through Z), numeric characters (0 through 9), or the underscore
|
|
(_).</p>
|
|
<p>Although not required, you can include one or more directories in the path
|
|
name. Each element of the path can be a maximum of 32 characters with the
|
|
total maximum path length of 256 characters. A path name can consist of any
|
|
alphabetic characters (A through Z), numeric characters (0 through 9), or
|
|
the underscore (_).</p>
|
|
<p>For ISO 9660 media containing Rock Ridge extensions, the length of each
|
|
element name is not restricted, but the total maximum path length is still
|
|
256 characters. The path name characters are not restricted, but are recommended
|
|
to consist of the POSIX portable file name character set (A through Z, a through
|
|
z, 0 through 9, period (.), underscore (_), or hyphen (-)).</p>
|
|
<p>File name searches are not case sensitive, meaning that you can use either
|
|
uppercase or lowercase characters to access existing files.</p>
|
|
<p>For ISO 9660 media containing Rock Ridge extensions, file searches are
|
|
case-sensitive. If no case-sensitive match is found, a mixed case match is
|
|
returned if it exists. If multiple mixed case matches exist on the volume,
|
|
an error will be returned indicating that ambiguous names exist on the media.
|
|
Some optical commands, such as Copy Optical (CPYOPT), are not supported when
|
|
duplicate, ambiguous file names exist. For example Rock Ridge allows files
|
|
ABC.ext and abc.EXT to exist in the same directory. This is not supported
|
|
by CPYOPT and may produce unpredictable results.</p>
|
|
<div class="section"><h4 class="sectiontitle">Directory and file security</h4><p>There is no direcotry-
|
|
and file-level security for ISO 9660 media. Volume-level security
|
|
is available through authorization lists.</p>
