<p>The FileListTransfer plugin is designed to send a list of files that have been read into the <strong>FileList</strong> class. It is similar to the <a href="directorydeltatransfer.html">DirectoryDeltaTransfer</a> plugin, except that it doesn't send deltas based on pre-existing files or actually write the files to disk. It solely handles the networking part of sending files.</p>
<p>Usage:</p>
<ol>
<li>Server: Call SetupReceive(...) with the address of a system to allow a file send, and a <strong>FileListTransferCBInterface</strong> derived callback handler to be called as the data arrives.</li>
<li>Client: Encode the files you want to send into the <strong>FileList</strong> class.</li>
<li>Client: Call Send(...) with your <strong>FileList</strong> class instance, a user-defined ID to identify this set of files, parameters to pass to RakPeerInterface::Send() or TCPInterface::Send(), and a boolean indicating if the files should be compressed or not. Compression is not very fast, so it's best to leave that off unless bandwidth is at a premium. </li>
</ol>
