Zip doesn't create when removing source directory after zip make

[TedAvery]

I can successfully ZIP a folder of files. The problem is that when I try to delete the source directory after creating the ZIP (line 4 below), the ZIP doesn't get created. Is there a way to ensure the ZIP has been finalised before I delete the source directory?

$batch_path = storage_path().$this->batch_base.'/'.$batch_name;
$zip_path = 'downloads/invoices/'.$batch_name.'.zip';
Zipper::make($zip_path)->add($batch_path);
File::deleteDirectory($batch_path);

try with close() at the end, this should flush the changes to the file system.

Yep that did it. Sorry, somehow I overlooked that in the documentation. Thanks a lot.
