Yahoo! Mail's new "Attach Large Files" app let anyone easily upload and send files of up to 100MB from their Yahoo! Mail accounts. The app, developed by YouSendIt, leverages Yahoo! Mail's powerful APIs and the Yahoo! Application Platform to enable this capability.
You can access the YouSendIt app by clicking on the "Attach Large Files" paper airplane icon in the Applications area of Yahoo! Mail.
From there, click on the "select files" button to attach files into your message. YouSendIt uploads those files and then opens an email compose window that includes a link to the file for download.
"The recipient can click on the "download" button within your message to retrieve your files. All files sent through YouSendIt are encrypted and then scanned by the system for viruses, so they'll arrive safely. YouSendIt will first go live to users in the U.S., and in the coming weeks to international users," said Yahoo!.
