Deleting file field's files via API not working or timing out

}

I've tried $page->tracks_upload->deleteAll(), removeAll(), $page->delete($t), $page->delete($t->name) ($page ones in the foreach loop), all kinds of things. Nothing seems to work. Pages are created fine and all, I just need these files deleted too.

This worked

	protected function addNewTracks($event) {
		$page = $event->arguments[0]; 
		$pages = wire('pages');
		if($page->template == 'tracks' && count($page->tracks_upload) > 0) {
			foreach($page->tracks_upload as $t) {
				$basename = str_replace(".{$t->ext}",'',$t->name);
				$p = new Page;
				$p->parent = $pages->get('/tracks/');
				$p->template = 'track';
				$p->title = $basename;
				$p->addStatus(Page::statusUnpublished)->save();
				$p->audio->add($t->filename);
				$p->save();
				$p->name = $p->id; $p->save();
				$this->message("Added new track {$p->title} by {$p->createdUser->name}");
			}
			$page->tracks_upload->removeAll();
			$page->save();
		}
	}
