Email has file size limitations and sometimes you want to share a file right away and you don't have time to setup dropbox or google drive on the computer you are using. With this service, you can quickly share a file and rest assured that the file will be destroyed 24 hours after you upload it. I personally have shared a file or folder on dropbox and find out months later the file or folder still being shared. You don't need to worry about that when using this service.
