I Have Files Or Folders
Choose the data-disc guide when you want photos, documents or other ordinary files on a CD or DVD. If those files are videos for a standalone player, first read Data DVD vs Video DVD so you choose the correct preparation route.
I Have An ISO
Use the ISO-to-CD/DVD guide to write the image contents as a disc. Use the image-building guide when your goal is to create a new ISO from your own file collection. The two directions need different tools.
I Have Music Or An Audio CD
Use the audio-CD creation guide for a playable track compilation. For a source music CD, choose the copying guide for an audio image or the collection-to-PC guide for separate WAV tracks.
I Searched For Online Burning
This site provides a Windows software download and instructions. The actual CD or DVD writing takes place on your PC, where the program can access your optical writer. A browser page alone is not the burning step.
My Disc Did Not Work
The disc-burning mistakes guide helps distinguish wrong project types from media and reading problems. Keep the log and identify whether the issue happens during writing or only when another device tries to play the disc.
