Heres the things you need:
File uploading class
Zip encoding class

..and finally unlink() for deletion

Only

$name = 'mydata1.txt';
$data = 'A Data String!';

$this->zip->add_data($name, $data);

// Write the zip file to a folder on your server. Name it "my_backup.zip"
$this->zip->archive('/path/to/directory/my_backup.zip');

I'm not sure. I see $this->zip->download('my_backup.zip'); and I don't want to download it.
I'll tray. Sorry for my bad English.
TNX !

Read harder There's method called $this->zip->archive() which you are looking for.
