YouSendIt is a large file email service that helps you get around email file attachment limits. YouSendIt stores up to a 1 gigabyte and emails the recipient a link to download the file for up to seven days (and an unspecified number of times). The recipient can also click a link to delete the file after downloading.
YouSendIt’s larger capacity makes it a more practical way to move your data from a CD-burnerless old computer to a new one (zip ‘em all up into one file first). Or send a TV show to a friend (a typical hour-long episode is around 600 megabytes.) Sending files of those sizes will be a time commitment, so plan ahead.
