E-Freight New services allow you to send oversized files across the Net.

You've just written up a lengthy contract and need to showit to a far-flung group of clients ASAP. Or maybe it's acomplex business proposal you've prepared--with complicatedspreadsheets, a set of PowerPoint slides and maybe even a narrationyou've recorded on your computer's hard drive. You couldsend paper copies or computer disks by overnight mail, butthere's no time. Faxing the papers would be faster, but yourslides would arrive only in black and white. Oh, you say, just sendthe materials via regular e-mail. Alas, beyond a couple ofmegabytes in size, large files often fail to traverse the Internetintact. And e-mail delivery is neither guaranteed nortraceable.

One solution: Use one of the Web's new document deliveryservices. They're specifically designed to transfer largedigital files--up to a full gigabyte--with complete, intact andsecure delivery guaranteed. By employing their own powerful serversas relay stations, these services get around the limits that manyISPs and corporations impose on the size of e-mails they'llhandle. And like their physical counterparts, such as FedEx andUPS, they provide notification when your intended recipients openthe files you send them.
