F*EX (Frams' Fast File EXchange) is a Web based service for sending very big files from one person to another. The sender uploads the file to the F*EX server and the recipient automatically gets a notification email with a download URL. Files are automatically deleted after download or an expiration date. The recipient and sender only need an email program and a Web browser. Sending to multiple recipients needs storage on the server only once. In contrast with other file transfer services, it has no file size limits at all and comes with shell tools for scripting up/downloading.
