File sizes are getting out of control. YouSendIt is a tool to overcome size limitations on email attachments, but it has one big drawbacks though: confidentiality. If you do not sign up for the premium version, anyone who gets her hands on the file link can download it.
One solution is Google Docs. Recently, Google updated the service and it is now possible to upload and download files that are not in Google's propriety format. Plugins such as OffiSync create a seamless integration between Microsoft Office and Google Docs. The advantages:
  • Tighter security
  • The ability to maintain one master document that you iterate, rather than emailing multiple versions of the same presentation around.
