Dropbox is a free service that lets you bring your photos, docs, and videos anywhere and share them easily. Dropbox was founded in 2007 by Drew Houston and Arash Ferdowsi, two MIT students tired of emailing files to themselves to work from more than one computer. Today, more than 45 million people across every continent use Dropbox to always have their stuff at hand, share with family and friends, and work on team projects.

Tutorial and Overview of Getting Started with Dropbox:

"While I do not necessarily encourage Professional School Counselors working from home, there are times when we must. Dropbox is a FREE resource that has allowed me to work on documents from home and store them in any other computer that it’s downloaded on, all without e-mailing yourself documents or bringing your work laptop or flashdrives home. When I return to work, it’s right there! Go to dropbox.com to watch a video and download."
-Kelly Johnson

"Dropbox is a fantastic substitute for your flash drive, but there's more to it than that. You can share folders with other users so that you don't have to email large files back and forth (pictures, videos, large pdf's, etc...). And every time you share with somebody, they increase your storage limit. Another alternative is Ubuntu One, which gives you 5G of storage space rather than the 2G from Dropbox."
-Rick Scheibner, School Counseling Matters
