<h2>get_filenames('<var>path/to/directory/</var>')</h2>
<p>Takes a server path as input and returns an array containing the names of all files contained within it. The file path
can optionally be added to the file names by setting the second parameter to TRUE.</p>
+<h2>get_dir_file_info('<var>path/to/directory/</var>')</h2>
+
+<p>Reads the specified directory and builds an array containing the filenames, filesize, dates, and permissions. Any sub-folders contained within the specified path are read as well.</p>
+
+<h2>get_file_info('<var>path/to/file</var>', <kbd>$file_information</kbd>)</h2>
+
+<p>Given a file and path, returns the name, path, size, date modified. Second parameter allows you to explicitly declare what information you want returned; options are: name, server_path, size, date, readable, writable, executable, fileperms. Returns FALSE if the file cannot be found.</p>
+
+<p class="important"><strong>Note:</strong> The "writable" uses the PHP function is_writable() which is known to have issues on the IIS webserver. Consider using fileperms instead, which returns information from PHP's fileperms() function.</p>
+<h2>get_mime_by_extension('<var>path/to/file/</var>')</h2>
+
+<p>Translates a file extension into a mime type based on config/mimes.php. Returns FALSE if it can't determine the type, or open the mime config file.</p>
+<p class="important"><strong>Note:</strong> This is not an accurate way of determining file mime types, and is here strictly as a convenience. It should not be used for security.</p>
