Once you have an account you can set up various folders to store whatever files you would like. You can invite people to share a folder with you giving them access to files saved in that folder; which is incredibly convenient if you have a large file that takes forever to send back and forth via e-mail.
Are you waiting for the catch? Tons of spam e-mails, pop ups, endless advertising...? To date I haven’t had any of that. The catch is that you are only given 2GB worth of storage memory to start. For anything larger you need to pay a small fee or you can earn more space by referring others. As I do not store large amounts of music or media files in there, the 2GB has been more than adequate for the past couple of years.
As I mentioned in an earlier post you get 25GB of free online storage space with any Hotmail or Windows Live account. However the draw back with that one is that it’s private and doesn’t download the handy dandy icons on your desktop. So I use the Drop Box as a quick fix for anything I need to get to right away and I use my Hotmail storage space for long term important things that I need to archive.
For practical uses for business I use it to share files between my laptop and the computer in my office. I also use it to get to files when I am away from both computers. As an example I was attempting to transfer a file to a client that I had saved to a USB Key, but it wasn’t working so I just logged into my web account and downloaded it from there. I also know of a small business with several employees but no central office. They all worked from their homes and used Drop Box as “Shared Drive” to communicate with one another.
So for small businesses or even for personal use I think Drop Box is definitely worth a try.
