<h2><a name="move">Move</a></h2>
<h3>Description</h3>
<p>Moves a file to a new file or directory, or collections of files to
a new directory.  By default, the
destination file is overwritten if it already exists.  When <var>overwrite</var> is
turned off, then files are only moved if the source file is newer than
the destination file, or when the destination file does not exist.</p>

<p><a href="../Types/resources.html#collection">Resource
Collection</a>s are used to select a group of files to move.  Only
file system based resource collections are supported, this includes <a
href="../Types/fileset.html">fileset</a>s, <a
href="../Types/filelist.html">filelist</a> and <a
href="../using.html#path">path</a>.  Prior to Apache Ant 1.7 only
<code>&lt;fileset&gt;</code> has been supported as a nested element.
To use a resource collection, the <code>todir</code> attribute must be
set.</p>

<p><b>Since Ant 1.6.3</b>, the <i>file</i> attribute may be used to move
(rename) an entire directory.  If <i>tofile</i> denotes an existing file, or
there is a directory by the same name in <i>todir</i>, the action will fail.
</p>

<h3>Parameters specified as nested elements</h3>
<h4>mapper</h4>
<p>You can define file name transformations by using a nested <a
href="../Types/mapper.html">mapper</a> element. The default mapper used by
<code>&lt;move&gt;</code> is the <a
href="../Types/mapper.html#identity-mapper">identity</a>.</p>
<p>Note that the source name handed to the mapper depends on the
resource collection you use.  If you use <code>&lt;fileset&gt;</code>
or any other collection that provides a base directory, the name
passed to the mapper will be a relative filename, relative to the base
directory.  In any other case the absolute filename of the source will
be used.</p>
<h4>filterchain</h4>
<p>The Move task supports nested <a href="../Types/filterchain.html">
FilterChain</a>s.</p>

<p>
If <code>&lt;filterset&gt;</code> and <code>&lt;filterchain&gt;</code> elements are used inside the
same <code>&lt;move&gt;</code> task, all <code>&lt;filterchain&gt;</code> elements are processed first
followed by <code>&lt;filterset&gt;</code> elements.
</p>
