Zeta Uploader is a service that allows users to send large files online free-of-charge. Users can enter one or more files and an e-mail address, and Zeta Uploader will then send a download link to the intended recipient. Anyone who knows the download URL can download the file unless the user chooses to password-protect it. The maximum uploadable file size is 500MB, and files remain downloadable for up to 30 days. The Zeta Uploader API allows users to access these functions programmatically via SOAP calls.
