$files->unzip nested folders?

[Spica]

Is the unzip method constructiong a nested folder hirarchy that is given in the zip? Or does it zip all files flat into one folder?

So, yes, this method unzips all nested files.

My use case, for anyone who may need:

<?
// hook into tutorial upload and unzip file into destination
wire()->addHookAfter("InputfieldFile::processInputFile", function(HookEvent $event)  {
    $pagefile = $event->argumentsByName('pagefile');
    // limit to a specific field {file_tutorial}, restricted to zip uploads
    if($pagefile->field->name != 'file_tutorial') return;
	// full disk path to your custom uploads directory
    $tutorialsBaseDirectory = $this->wire('config')->paths->assets . 'tutorials/';
	// extend path with custom directory nam corresponding to page id
    $pageIdDirectory = $tutorialsBaseDirectory . $pagefile->page->id . "/";
    // extend path with custom directory name from the filenme without extention
    $tutorialDirectory = $pageIdDirectory . $pagefile->basename($ext = false);
    // use ProcessWire's $files API
    // @see: http://processwire.com/api/ref/files/
    $files = $this->wire('files');
    // Remove directory and its files after ensuring $pathname is somewhere within /site/assets/
	$files->rmdir($pageIdDirectory, true, [ 'limitPath' => $tutorialsBaseDirectory ]);
    // make tutorials id directory correspondig to ressources id
    if($files->mkdir($tutorialDirectory, true)) {
	   // directory created: /site/assets/tutorials/id/filenameWithoutExtension
	}
    // get zipfile and destination and unzip
	$zip = $pagefile->filename;
	$dst = $tutorialDirectory;
	$items = $files->unzip($zip, $dst);
});

The script takes an uploaded zip and unzips it into the destination folder. As it has an index.html I can point a link to it.
