Another good thing is that you can retrieve any of your file from ANY computer by just logging on to the dropbox site and you have all your files stored there too!
The best thing about it is that its FREE. Yes you heard it right. FREE. You have 2gig for starters and you can increase it through a referral program up t0 10gig.
I want that free 10gig of storage so if you are interested, just use my referral link and start syncing and sharing your files!!!
PS. Dropbox also have mobile version for the Iphone and Anroid. So what are you waaitng for. The best solution for files syncing around. Trust me! I have used it personally and its cool!
