CD-Tools

Helios is a frontend for "cdrecord" and "mkisofs". Helios burns data, audio and bootable CDs. Data CDs can be done without creating an image file on hard disk.

The Disk Settings Box
Is where you define what kind of disc mode you want to use. You can select between the following disc types: Data CD, Audio CD, Bootable CD, CD Extra and Data DVD.

The content of this settings is relative to what disc type you have chosen.

When you choose Data CD you will, with the mkisofs, be able to create many different filesystem images:

- MacOS HFS (hybrid)
- UNIX RockRidge
- Windows Joliet
- ISO 9660
- ISO 9660 with long filenames
- UDF

Please use rewritable discs first to test whether it works with your CD writer or not or burn in simulation mode.

The Info Box
The box contains the following information about the current project you are about to burn to disc:

- Total CD Size: The disc size of the file system image in MB when making Data CDs. The size of real audio date when you are creating an audio CD.
- Total CD Duration: The playing time of the disc (useful for Audio CDs).
- Estimated Time: The time which seems to be needed to burn the project to disc.

The two last lines have the task of counting the total number of files and folders in the project.

The values shown in the info box are updated when you press the Update button. You can also define an update frequency in the preferences.

The File List
It's in this area of Helios main window where you drop the files that you want to have part of your project (CD). Helios accepts any file you drag from a Tracker window to the File List (except when you have opened an Audio CD project and drop a non-audio file type).

#### The Menus

Image

- Read CD Image... (ALT+R): Reads the whole CD inserted to a file which must be entered in the small window which appears after clicking this menu item.
- Create Image File... (ALT+F) writes the project as a file system image file that can be burnt to CD with another burning application which supports image writing (CD Manager and CDBurner).
