A software tool automatically places files and folders of a software program within segments of a DVD. The segments are defined by security placeholders, and the disposition of the placeholders is initially randomly determined, consistent with predefined rules. The placeholders are included on the disc to hinder unauthorized copying. A developer generally defines the order in which the files and folders are to be laid out, and the software tool automatically places the files and folders, filling successive segments and shifting the placeholders to accommodate files that will not fit in a current segment. However, any movement of the placeholders must be done by the tool and is only permitted if the new disposition of the placeholder is in accord with the predefined rules. A user can manually modify the automated layout, and in response, the files and folders are automatically shifted to accommodate the changes introduced by the user.
