Dropbox has released 1.0 version of its dekstop->cloud service that reduces the resource size, offers support for extended attributes, selective sync, and a shiny new installation wizard.

“Huge performance enhancements – Dropbox 1.0 is strong enough to sync your entire digital life yet still lightweight and fast. We completely re-architected the client-side sync engine to optimize the response time, scale, and resource consumption. Keeping track of millions of files can require lots of memory if not done properly. This version reduces memory usage by up to 50%. It’s speedier and more efficient when handling big changes to your Dropbox while ensuring that smaller changes remain quick.

Better user experience – We’ve completely redesigned our initial setup wizard on all three platforms to make it easier to get started using Dropbox. The preference menus are more organized, intuitive, and snazzy. We’ve also rewritten our Mac OS X version to only use Cocoa so Dropbox looks and feels much more native on the Mac. This also brings down the Mac download size by 20%

Selective Sync – If you have a netbook or a computer with a tiny hard drive, syncing your entire Dropbox isn’t always a great idea. You also might not want certain files on your home computer to pop up on your work computer. Selective Sync solves these problems! You now can choose which folders get downloaded to which computers. This saves you time so you don’t have to sync stuff you don’t need“ – blog
