I have developed a hack to had the capacity to unzip and untar files in the media manager component of Joomla! 1.5. It work like the delete function, you check the file and you click on the icon to unzip the selected file. It generate a folder with the same name of the selected file.

This hack is available here at the end of the post. Just copy it at the root of your site. By hand it work like this.

Open the file administrator/component/com_media/views/media/view.html.php and after the line 106

    /* (...) */
    // Add a delete button
    $title = JText::_('Delete');
    $dhtml = "<a href=\"#\" onclick=\"MediaManager.submit('folder.delete')\"
      class=\"toolbar\">
                <span class=\"icon-32-delete\" title=\"$title\"
                  type=\"Custom\"></span>
                $title</a>";
    $bar->appendButton( 'Custom', $dhtml, 'delete' );
    /* (...) */

add

    /* (...) */
    // Add a Unzip button
    $title = JText::_('Unzip');
    $dhtml = "<a href=\"#\" onclick=\"MediaManager.submit('folder.unzip')\"
      class=\"toolbar\">
                <span class=\"icon-32-unarchive\" title=\"$title\"
                  type=\"Custom\"></span>
                $title</a>";
    $bar->appendButton( 'Custom', $dhtml, 'unzip' );
    /* (...) */

This add the icon button on the top of the media manager near the delete button. Then open the file administrator/component/com_media/controllers/folder.php and add after the delete function

    /* (...) */
    function unzip() {
        global $mainframe;
 
        // Set FTP credentials, if given
        jimport('joomla.client.helper');
        JClientHelper::setCredentialsFromRequest('ftp');
 
        // Get some data from the request
        $tmpl    = JRequest::getCmd( 'tmpl' );
        $paths    = JRequest::getVar( 'rm', array(), '', 'array' );
        $folder = JRequest::getVar( 'folder', '', '', 'path');
 
        // Initialize variables
        $msg = array();
        $ret = true;
 
        if (count($paths)) {
            foreach ($paths as $path)
            {
                if ($path !== JFilterInput::clean($path, 'path')) {
                    JError::raiseWarning(100, JText::_('Impossible de
                      decompresser:').htmlspecialchars($path, ENT_COMPAT,
                      'UTF-8').' '.JText::_('WARNDIRNAME'));
                    continue;
                }
 
                $fullPath = JPath::clean(COM_MEDIA_BASE.DS.$folder.DS.$path);
 
                if (is_file($fullPath)) {
                    $ext = JFile::getExt(strtolower($fullPath));
                        $pathdir = $fullPath;
                        if($ext != 'gz') {
                            $pathdir = str_replace( ".".$ext, "",$pathdir);
                        }
                    else {
                        $pathdir = str_replace( ".".$ext, "",$pathdir);
                        $pathdir = str_replace( ".tar", "",$pathdir);
                    }
 
                    jimport('joomla.filesystem.*');
                    jimport('joomla.filesystem.archive');
                    JFolder::create($pathdir);
                    JFile::write($pathdir.DS."index.html", "<html>\n<body
                      bgcolor=\"#FFFFFF\">\n</body>\n</html>");
                    JArchive::extract($fullPath, $pathdir);
 
 
                } else if (is_dir($fullPath)) {
                    JError::raiseWarning(100, JText::_('Imossible de
                      decompresser:').$fullPath.' '.JText::_('Pas un fichier
                      ZIP'));
                }
            }
        }
        if ($tmpl == 'component') {
            // We are inside the iframe
            $mainframe->redirect('index.php?option=com_media&view=mediaList&
              folder='.$folder.'&tmpl=component');
        } else {
            $mainframe->redirect('index.php?option=com_media&folder='.$folder);
        }
    }
    /* (...) */

That's all. My hack use the joomla.filesystem.archive librairy of joomla 1.5 and work with zip, tar and gz extension.
