Today, we’re pleased to announce that people using Yahoo! Mail now have the ability to attach up to 100MB of files to each email using drop.io’s new Attach Large Files application. Best of all, it only takes one click and there is no sign-up or registration!

Drop.io is the simplest way to privately share exactly what you want with whom you want online – all in real-time and across all platforms (web, mobile and more).

Our application makes it easier to share groups of photos, documents, movies and more, by combining the power of drop.io as a robust media & file sharing platform with Yahoo! Mail, one of the world’s most popular email services.

People can access the Attach Large Files app from the Applications Box in the lower left-hand corner of their Yahoo! Mail inbox and using the app is simple:

1. Click “Attach Large Files” — this brings you to the drop.io welcome page
2. Next click “Select Files” — add as many files from your computer as you want up to 100MB. You’ll recognize drop.io’s distinct upload interface that displays the queued files, their file size and allows you to cancel any of them either before or during upload.
3. Next click “Upload and Compose Email” – users are brought to a new email, populated with thumbnails and links to view and download the attachments.
