Dropbox will enable you to instantly store your files online and optionally share them.

Once Dropbox is installed, any file you drop into your folder will synchronize and be available on any other computer you've installed it on. Also, any changes you make to files in it will sync to your other computers, instantly.

You can undelete files and even go through previous versions.

Share files and folders with anyone even if they're not Dropbox users.

Dropbox is fast because it only updates the parts that have changed, rather than the entire file. All files are transported over SSL and encrypted using AES-256 for security.

When using any Beta we recommend that you create a system restore point before proceeding just to be on the safe side.
