Dropbox is one of the most useful programs I have used as a student and teacher. All the things I work on at school (on my school computer) are instantly uploaded to my computer at home. I can make a change at home and the files will be changed at school. If I need a file and I am away from these computers, I can access my Dropbox from anywhere and download the files I need. I can also access them on my iPhone. Dropbox is super convenient and I don’t ever need my USB drive.
You get 2GB of storage for free, and 500mb for referring someone. If you signup through this link, you will get an addition 500mb too!
So, please do me a favor and try out Dropbox!
