Users will be able to access those files from mobile devices as well as share them with other Dropbox users who you invite to view the files.

After downloading the software, Dropbox creates a folder named “Dropbox” on your computer. Any files you put in that folder can be accessed from other devices, or shared with other uses who you invite.

“One thing my family and I did is create a folder named ‘family share.’ It’s in my Dropbox, my family’s Dropbox, so we can all access that information,” says Tom Schmit at First Tech Computers in Minneapolis, who uses the service to share family pictures from the holidays.

The download is free, and with it you’ll be able to store 2 gigabytes of data. More storage will cost you.
