esyurl - yet another URL shortening service

Esyurl is a URL shortening service that has been online for not long. Compared with other similar services, Esyurl has a special function - it can also upload files. However, it only allows uploading .rar, .zip, .tar.gz types of files (Esyurl mainly supports Firefox and also provides a toolbar for Firefox), and the file size must be less than 2M. Once uploaded, the file will be given a short URL directly. Currently, due to being online for not long, the shortened URLs are still very short. For example, after shortening the URL of my blog, it becomes http://esyurl.com/5s.
