<h1>&lt;copy&gt;</h1>
<p> Copies a file, a directory, or set of files to a new file or directory. </p>
<p> Files are only copied if the source file is newer than the destination file, or if the destination file does not exist. However, you can explicitly overwrite files with the <code>overwrite</code> attribute. </p>
<p> When a <a href="../types/fileset.html">&lt;fileset&gt;</a> is used to select files to copy, the <code>todir</code> attribute must be set. Files that are located under the base directory of the <a href="../types/fileset.html">&lt;fileset&gt;</a> will be copied to a directory under the destination directory matching the path relative to the base directory of the <a href="../types/fileset.html">&lt;fileset&gt;</a>, unless the <code>flatten</code> attribute is set to <b>true</b>. </p>
<p> Files that are not located under the the base directory of the <a href="../types/fileset.html">&lt;fileset&gt;</a> will be copied directly under to the destination directory, regardless of the value of the <code>flatten</code> attribute. </p>
<h4 xmlns="">Encoding</h4>
<p> Unless an encoding is specified, the encoding associated with the system's current ANSI code page is used. </p>
<p> An UTF-8, little-endian Unicode, and big-endian Unicode encoded text file is automatically recognized, if the file starts with the appropriate byte order marks. </p>
<p class="i2">
<b>Note:</b> If you employ filters in your copy operation, you should limit the copy to text files. Binary files will be corrupted by the copy operation. </p>
