Download zip

Hey everyone, I’m new to this forum and I’m a flash website developer. I’m trying to create a button on my website that allows you to download a .pdf file or a zip file when you click on the flash button. I want an open/save window to pop up so that the person can either open the file locally, or save it to their pc. Does anyone know the code that I would put into the flash button so that this can be possible? thanks for your time.
