16 ISO Recorder
This one-trick-pony download does its thing exceedingly well. ISO Recorder lets you burn ISO files to CD or DVD. An ISO file is a single, large file that – when burned to a CD or DVD – contains many files, a file system and data and can be used to install an OS.
For example, Windows Vista betas were made available as ISO files; if you wanted to install the beta, you had to download the ISO file, burn it to DVD and then boot from the DVD to install the unfinished version of Windows Vista. (In some instances, ISO files can be used for other purposes, such as creating music or video, but ISO Recorder won’t create images of audio or video CDs.)
The program can create ISO files as well as burn them. ISO Recorder integrates itself directly into Windows Explorer. Right-click an ISO file and then follow the instructions to burn it to CD or DVD.
