Another useful free tool for post graduates and academics. YouSendIt is a secure online file transfer service for sending large files that can’t be squeezed through your inbox. This service is useful for all sorts of situations, particularly if you’re looking for a high-speed (quicker, cheaper, perhaps greener?) alternative to putting a CD in the post. Their ‘Lite’ service is free and supports up to 1GB per month. Perfect if you’re looking for an easy way to share audio or video files with third parties for collaboration or transcription, without using FTP.
