Ashampoo Burning Studio 2019 is a free disc burning suite with some interesting extras.
The core of the program works much like the competition. Choose your project type - a data disc, maybe an audio CD - then drag and drop your source files onto the interface, and you can be burning your CD, DVD or Blu-ray disc in a couple of clicks.
But Burning Studio can also create Autostart discs, which display interactive menus that appear when the disc is inserted. These can launch files or documents, send an email, link to a web page and more, and are a great way to present information to the recipient of your disc.
Image handling is another plus, with tools to burn images (ASHDISC, CUE/ BIN, ISO, IMG), browse them, or create images from files or other discs.
If you're looking to burn audio CDs then you'll appreciate the wide file format support: MP3, WMA, OGG, APE, OPUS, FLAC, CDA and WAV.
There's also a simple file backup tool, a cover designer, and a disc copier, and there are some advanced tweaks for experts (set file system, boot options, more).
The only weak spot is movies, because the program can only burn video DVDs and Blu-rays from a VIDEO_TS (or similar) source folder. But you can fix that - and add a few other features - by upgrading to the full commercial edition, Ashampoo Burning 20.
