From an 'interface' point of view, it makes sense to do this all in one step and (as chromatic and Skeeve suggest) avoid using a temporary file. Having a second 'confirm' screen is not only complicating your code, but making it more troublesome for the user.

It's unlikely that the user will remember specific filenames, so unless your second "directory list" screen also includes thumbnails ("are you sure you wanted these pictures?") , you may as well just use the one main screen full of checkboxes, and the 'Download' button causes the zip file to be written directly to the browser (using Archive::Zip's writeToFileHandle() method I should think - haven't used it myself, but it looks that way from the docs).

Cheers,Ben.
