For a couple of years now I've been using -- nay, relying on -- the free YouSendIt file sending service. It's one of those free web tools that lets you send huge files to someone else if they're too big to send via email. But the folks at YouSendIt have now introduced a much easier way to send files if you're an Outlook user.

If you use Outlook 2003/2007 for email, you can now download a free plug-in for YouSendIt, a service that lets you send up to 100MB of files to someone for free; the recipient receives an email from YouSendIt with a link to download the file(s) to their computer.

Before this Outlook plug-in, you had to visit the site, log in (unless you chose for it to remember you), cut and paste an email address into the "To" field and browse your hard drive to find the files you wanted to send.

Now, when you send an email with an attachment within Outlook, a small YouSendIt window pops up, asking if you'd like to use YouSendIt instead of Outlook. Personally, I entered the settings area of this plug-in and chose for it to pop up when the files I'm sending are bigger than 5MB in size. Try it out for free by downloading the plug-in at YouSendIt online.
