Dropbox is about file sharing and syncing needs. With the service, you can share your files with anyone you want using a public URL while at the same time you can do some backups and syncs, and access your files from any browser or mobile device.

Dropbox works just like any other folder on your computer, but with a few differences. With its web interface, you can drag and drop to move files around. Any files or folders inside Dropbox will get synchronized to Dropbox's servers and any other computer linked to your account. It may remind you of how Nokia Phone Suite works, but it is actually more like an intranet environment. You have your shared documents for sharing and public folders for non-Dropbox users. Any files in here will be given a link that you can send to others in e-mails, IMs, blogs, etc. without requiring people to sign up for Dropbox. And this way it is more like RapidShare or MegaUpload. And if you want to keep the files for yourself, just don't put your files in public or shared documents folders.

They claimed that your files are always safe since all data is transferred over SSL and encrypted with AES-256 before storage.

Dropbox opened up to public on 9/11 since it was in an invite only beta for almost two years. 2 GB of storage space is given for free at the moment. Its desktop client is available for all operating systems, Windows, Mac and Linux. If 2 GB is too limited, you can get a 50GB Dropbox for $9.99 per month.

There are other similar services that you might be interested to look around, such as Syncplicity and Live Mesh. Have a nice sharing and greater mobility! And don't forget to have a strong password.
