Dropbox has finally broken free from the shackles of its public beta period with the launch of  Dropbox 1.0.

Version 1.0 adds some nifty new features to the equation as well, including a new selective-sync option, where certain devices will only sync with certain folders (handy if you've got limited space on a machine) a 50 per cent reduction in memory usage, a new Cocoa engine for the Mac version and extended attribute sync for hidden file information.

If you're not familiar with Dropbox, then you should give it a try as it really is one of the most useful tools available if you use multiple devices to access the web.

Not only is it compatible across all of your PCs (Windows, Mac or Linux) there are also apps available for iPhone, Android and BlackBerry handsets as well.

The idea behind Dropbox is that you create a centralised folder that you have on all your computers and devices that automatically sync whenever you have a web connection. Basically, whenever you make a change to a file in the Dropbox folder (on any of your devices) and save it, it will automatically update on all of your other computers when they are connected to the web.

With online web access as well backing up your local files, you can also access previous versions of your files, as well as recovering deleted items. Plus, the web portal means you have access to all of your Dropbox folder files wherever you are - even on computers without Dropbox installed onto them.

Dropbox has a free 2GB space option, and there are premium versions as well if you need more storage.

If you're not already using Dropbox, but fancy a spin up in the cloud then use this Dropbox link to get yourself an extra 250MB of space on top of the 2GB that you can get for free.
