Appending Data to a Data DVD
When creating a data DVD you can choose whether to keep the writing session open to make a disc appendable.
 Appendable Writing
With this option more data may be added to a disc as long as there is space available. The recording session stays
open until the disc is full. Although the space on the disc may be used efficiently, a disc written incrementally may
not be compatible with all DVD drives.
 Non-appendable Writing
With this option all the data is written at one time and the session is closed, even if there is more space available
on the disc. No further data may be stored on the disc. Non-appendable discs are more compatible with different
DVD drives.
The table below describes the writing method for different media types for appendable and non-appendable writing.
Writing Method
Media Type Appendable Non-appendable
DVD-R N ot c urrently s upported Disc at once
DVD-RW Not currently supported Disc at once
DVD+R Multi-session Disc at once
DVD+RW Single-session Disc at once
The format will be UDF with Joliet in every case. UDF (Universal Disk Format) is a File System. Joliet is an extension of the
ISO 9660 standard to allow CDs to be written using long filenames and Unicode on Windows.
