zip class

I want to use a zip creation class, so users can download files from my site.

I found this.

The problem is that this class show all the path of the zip folders (c:/dir/downloadeddir/…) since the downloaded folder is the /downloadeddir/ and I thing it is not so good for obvious reasons.

Is there any good zip cration files? ?

I thing the last choice is to create my own class. :)
