YouSendIt is a client application for a service that lets you send files by email. The YouSendIt service will host the files you send, and will send to the recipient a direct download link to those files. In order to use the service, you will need to open an account with the service. You can open a Lite (free) account that will allow you to send one file per message, with a maximum size of 100 Mb. and 100 downloads. Or you can get a Pro, Business or Corporate account. You can compare them at the developer´s site. The YouSendIt interface will let you send files to any email account from its interface, that´s similar to any email client. You will be able to include a subject and a brief message with your file. Your recipient will receive a message from YouSendIt, the message you sent and a direct link to the file you uploaded. You will also receive a message to the address you provided upon registration, telling you that the file has been sent. You can set expiration dates for your files, and upload compressed folders as one single file. The main difference between this 2.2 version an the older ones is that the lite account now allows to use more features, and that certain business accounts are not available anymore. This version seems to be faster, too.
