Sending large files, being able to track how long they take at certain senders - really simple way of sending large sized videos and documents around without any hassle! I've found that most customers get their files via email aswell if required so this has limited its uses somewhat but it does still help with getting larger attachments out quicker than some options. For our purposes we needed a reliable service which was convenient. This could have been more expensive per GB compared to others (eg Skydrive), however in reality you would almost certainly also be uploading your own data too (SkyDrive) meaning costs probably wouldn't differ much anyway. Using this solution means we don’t need anyone else to upload/upload using FTP etc so saves everyone time. I love that it's easy to send files securely, you don't have to worry about someone getting into your computer. You can also easily add multiple people to a file so you don't have to send a file over again if they change their mind. It's not free so there is a small fee. But, they offer discounts to students and teachers. So, try them out! They're great at what they do and they're very trustworthy. Sending secure documents between individuals in my classroom. Easy way to share files with my students.
