Share: Downloads: Editor's Collection Deserving Donationware, Part I: Free Favorites Worth Paying For I turn to the same software time and again. Some I did not have to pay for, thanks to the generosity of hard-working developers who share their creations for free, asking only for a donation from those who are willing and able. I looked through my Start menu and taskbar for those applications I take for granted all year long. If you're already using these, now is a great time to support them or their causes. And if any are new to you, you're in for a treat. --Erez Zukerman Browse DownloadsAntivirus & Security • Design & Multimedia • Utilities • Games • Chat, Email, & the Web • Sponsored Downloads Cucusoft DVD Ripper+Video Converter Ultimate SuiteEnjoy your audio and video on any device with Cucusoft DVD Ripper + Video converter Ultimate.
