DropBox 1.0 Version

At the very least, you can use Dropbox to automatically backup a subset of your files, and to access them when traveling. You can also use the service to easily share files with friends and coworkers. Just right click on a folder and select “Share”. You’ll be taken to a webpage where you can enter the email addresses of who you want to share the folder with. When your friends add files to that shared folder, they will automatically get downloaded to your machine in addition to getting backed up online. If you have Growl installed on the Mac, it’s quite impressive to see your friends’ files magically show up.

It just works!
Dropbox works just like any other folder on your computer, but with a few differences.

Here's how it works:
Drag and drop to move files around, just like you normally would
Any files or folders inside Dropbox will get synchronized to Dropbox's servers and any other computer linked to your account.
Green checkmarks will appear on top of your files to let you know that they're synced and up to date.

Your files are always safe. All data is transferred over SSL and encrypted with AES-256 before storage.

Worry-free Syncing
Dropbox keeps track of every change made to any of its contents. Any changes are instantly and automatically sent to any other computer linked to your Dropbox. The Dropbox clients for Windows, Mac and Linux all play nice with one another too!
Dropbox is also smart with how it tracks changes to files. Every time you make a change, Dropbox only transfers the piece of the file that changed (also known as block-level or delta sync), making it easy to work with big files like Photoshop or Powerpoint documents.
Not at any of your computers and want to grab one of your files? Just hop onto Dropbox's web interface for access to your files from anywhere in the world.
The web interface is your Dropbox away from home. Download your files to computers without the Dropbox client, or upload new files to be synced to all your computers.

Dropbox's web interface is also like a virtual time machine that remembers every change you ever make. View or restore any previous versions of a given file. You can even undelete files that you may have accidentally trashed.Dropbox's shared folders make it easy for you to share a bunch of stuff with other people. This makes Dropbox perfect for team projects, music/video editing, and much more.

Any member of a shared folder can add, edit and delete the contents within.Collaborators of your shared folder won't have access to any of your files outside of that folder.Changes made to a shared folder are instantly sent to every member of that folder.Need to share some files with non-Dropbox users? Just drop files into your Public folder. 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.
Want to share your pictures with friends and family? Just create a folder within the Photos folder and drop your pictures inside. These folders will be viewable in a gallery on our web interface. Galleries in your Photos folder also have a unique web address that you can share with others (non-Dropbox users too!) through e-mail, instant messaging, or blogs.
