Filemail is #1 in

Filemail is a web-based file sharing system that you can use to send an unlimited number of files to anyone who has an email address. With no registration needed, you can send any file just by selecting it from your PC through the Flash-based interface, set the options, such as the number of days the file will be available for, type the receiver's email, and click send. When the progress bar will finish, an email will be sent to your friend with the download link.
