Disc Spanning
If you are creating a Mac Only or Mac & PC data disc, you can record large files and folders, even if they exceed the recording capacity of a single disc. If you do, Toast advises you of approximately how many blank discs are needed, and automatically spans the data across them.
The completed group of discs is called a disc set. Each disc in the set contains an index of the contents and location for every file and folder in the set.
To span discsAs you add data to the Content Area, Toast displays information about the number of discs you will need for recording. Click the disc capacity drop-down menu next to the Space indicator to adjust the information for CD, DVD, or Blu-ray discs.
2 Record your disc.
Toast will prompt you to insert each blank disc while recording.
To not span discs• To not have your data spanned across discs, remove files or folders from the Content Area until the left side of the Toast window indicates that the contents will fit on a single disc.
