WeTransfer web app addresses a common roadblock that those of you who send large files certainly run into using your standard email client. The service allows users to transfer and share large files (up to 2 GB) really easily. As an added bonus, there is no need to register, so you can get started sharing your files immediately without needing to fill out your birthday, zip code and blood type.
When you upload your document to the WeTransfer web app, the recipient receives an email with a link to a file that they can download. The file has an expiry date of two weeks after the initial upload. By using the cloud to store huge files temporarily, the WeTransfer web app has created a product that is certain to gain some niche popularity.
