## Description

A `Filename` is the name of a file on a local or network disk. It may be a simple name or may include a path or other elements specific to the operating system.

### Processing expectations

Formatted inline. The `MoreInfo` attribute can help generate a link or query to retrieve additional information.

### Future Changes

The content model of `Filename` will be constrained to `(#PCDATA | Replaceable | InlineGraphic)` in DocBook V4.0.

### Future Changes

Filename extensions can be explicitly identified with the `extension` class value.

### Parents

These elements contain filename: `action`, `application`, `attribution`, `bibliomisc`, `bridgehead`, `citation`, `citetitle`, `classsynopsisinfo`, `command`, `computeroutput`, `database`, `emphasis`, `entry`, `filename`, `foreignphrase`, `funcparams`, `funcsynopsisinfo`, `function`, `glosssee`, `glossseealso`, `glossterm`, `hardware`, `interfacename`, `keycap`, `lineannotation`, `link`, `literal`, `literallayout`, `lotentry`, `member`, `msgaud`, `olink`, `option`, `optional`, `para`, `parameter`, `phrase`, `primary`, `primaryie`, `productname`, `programlisting`, `property`, `quote`, `refdescriptor`, `refentrytitle`, `refname`, `refpurpose`, `remark`, `screen`, `screeninfo`, `secondary`, `secondaryie`, `see`, `seealso`, `seealsoie`, `seeie`, `seg`, `segtitle`, `simpara`, `subtitle`, `synopsis`, `systemitem`, `term`, `tertiary`, `tertiaryie`, `title`, `titleabbrev`, `tocback`, `tocentry`, `tocfront`, `trademark`, `ulink`, `userinput`.

### Children

The following elements occur in filename: `action`, `anchor`, `application`, `beginpage`, `classname`, `command`, `computeroutput`, `constant`, `database`, `email`, `envar`, `errorcode`, `errorname`, `errortext`, `errortype`, `exceptionname`, `filename`, `function`, `guibutton`, `guiicon`, `guilabel`, `guimenu`, `guimenuitem`, `guisubmenu`, `hardware`, `indexterm`, `inlinegraphic`, `inlinemediaobject`, `interface`, `interfacename`, `keycap`, `keycode`, `keycombo`, `keysym`, `link`, `literal`, `markup`, `medialabel`, `menuchoice`, `methodname`, `mousebutton`, `nonterminal`, `olink`, `ooclass`, `ooexception`, `oointerface`, `option`, `optional`, `parameter`, `prompt`, `property`, `remark`, `replaceable`, `returnvalue`, `sgmltag`, `structfield`, `structname`, `subscript`, `superscript`, `symbol`, `systemitem`, `token`, `type`, `ulink`, `userinput`, `varname`.

## Attributes

class

  `Class` allows the author to identify particular kinds of files.

moreinfo

  If `MoreInfo` is set to `RefEntry`, it implies that a `RefEntry` exists which further describes the `Filename`.

path

  `Path` contains the search path, possibly in a system or application specific form, on which the file can be found.

## See Also

`application`, `computeroutput`, `database`, `envar`, `hardware`, `medialabel`, `productname`, `prompt`, `systemitem`, `userinput`.

## Examples

    The symbolic constants for error numbers are defined in
    <filename class='headerfile'>errno.h</filename> in
    <filename class='directory'>/usr/include/sys</filename>.
    </para>

The symbolic constants for error numbers are defined in `errno.h` in `/usr/include/sys`.

For additional examples, see also `constant`, `errorcode`, `keycap`, `keycode`, `keysym`, `literal`, `variablelist`.
