MEGA just launched a sync desktop tool for Window today. For those who don't know, MEGA is a new service launched by Megaupload founder Kim Dotcom which offers 50 GB storage for free accounts holders. Your data is secured with 2048-bit RSA end-to-end encryption. Data uploaded is encrypted on the uploading device before it is sent out to the Internet, and data downloaded is decrypted only after it has arrived on the downloading device.
The release of the Windows sync client follows the launch of the mobile MEGA app for Android and iOS. Linux and Mac versions will be released soon.
