Dropbox enables you to upload your files or folders to the cloud to be able to access them from the web browser or any Dropbox-compatible device.

It's compatible not only with Windows but also with Mac OS X, Linux, Android, iOS, Windows Phone, and Blackberry OS.

In order to start using Dropbox, you must create an account (you get 2 Gb of free storage). You can either set the tool to sync all the folders in your Dropbox, or you can use "Selective Sync" to choose particular ones.

Basically, Dropbox installs a folder on your computer in which you can copy or move data to share online. This means that if you want to access your Dropbox files from another location, simply log in with your username and password.

You can view, download or upload contents directly in the web browser if you don't have the Dropbox application installed on the computer.

Of course, if you want, for example, to download your files shared on Dropbox from another computer, the job will be much easier and faster if Dropbox is installed on that particular computer.

In the online browser you can search for files and folders in your Dropbox, create a new folder, view deleted files and events (similar to a log file), send invitations to your friends, and more.

In the 'Preferences' menu, you can disable desktop notifications and the LAN sync, unlink the computer to the current account to add a different one, set the download and upload rate, configure proxy settings, input the Dropbox location, change the interface language, and more.

The program uses a moderate amount of system resources and includes a very comprehensive documentation, oriented towards helping users get around.

The bottom line is that Dropbox provides one of the simplest solutions for sharing data online and we strongly recommend it to all users.
