ULEAD BURN.NOW USER GUIDE 41
After clicking the Burn button in the Burning Options dialog box, the program checks your disc and prompts you to confirm if you want to span your data. Clicking Yes opens the Span Disc Options dialog box for you to select the way your data will be arranged.
Fast (same file order) arranges your files in their originally sequence. Although this method may require more disc space, it is the faster and easier way to burn to multiple discs.
Optimize (minimum number of discs) rearranges your files to save on disc space. Processing time may take longer.
Clicking OK continues the disc spanning process.
When burning multiple discs, use discs of the same brand and media type to avoid possible differences in size.
The Span disc function cannot be applied if Burn with synchronization info is selected under Advanced Settings in the Burning Options dialog box.
A single large file cannot be spanned into multiple discs.
