Saving The Current Disc Image File
Once a data disc image has been created, it must be saved for the
DIRECTOR to use it as a data source for recording. Disc images can either
be saved as script files (with an “ISC” extension) or physical image files
(with an “ISO” extension).
A script file (ISC) contains pointers to the source data files and is used as a
guide at the time of recording the CD. Since a script file does not include
the source data it is best used when producing unique projects with dynamic
content, or when the source data will always be available to the
DIRECTOR. Or, if producing software, a “static” image would be best to
ensure content.
A physical image file (ISO) is an exact replica of the final CD and contains
all of the source data. It is therefore best used when producing static
projects that are recorded on a regular basis, and when source data will not
always be available to the DIRECTOR. Please note that, depending upon
the amount of data to be recorded, a physical image file can occupy as much
as 700 MB of hard disk space.
