A disk image is a discrete electronic representation of an individual volume; the image contains all the information to make an exact duplicate of the original. When you use disk images, the volume as a whole has been duplicated correctly and completely.
DiskScripts
A DiskScript is a special file containing commands that instruct Disk Copy 6.1 or later to perform an action on a list of disk images.The most common DiskScripts are to install software and to make floppies from a specific set of disk images.
Disk Copy 6.1
Disk Copy 6.1 is a utility application that is required in order to use DiskScripts and the NDIF compressed disk image format. Disk Copy 6.1 or later will also work with Disk Copy 4.2 disk images. More information is available in the the Disk Copy 6.1 Manual and Quick Reference Guide.
Installing software using DiskScripts and Disk Images
Using DiskScripts and Disk Copy 6.1 or later, you do not have to make floppies from disk images to install software; you can install directly from the disk images by mounting them on the desktop.
To install software using a DiskScript, simply double-click on the DiskScript (the “.scr” file) whose name indicates it is an install DiskScript. Disk Copy 6.1 or later will launch, present a progress dialog, icons for mounted volumes will appear on the desktop, and the Installer will launch.
Making floppies from disk images
To make floppies from disk images, select one or more disk images and double-click while pressing the Option key. This only works for NDIF images (not Disk Copy 4.2 disk images).
Disk Copy 6.1 or later requires PC Exchange to make floppies from disk images that contain DOS or ProDOS volumes, such as a PC drive container or a DOS-formatted floppy. To make DMF (a 1.7 MB PC format) floppies, Disk Copy 6.1 or later requires a SuperDrive and Mac OS 7.6 or later, which includes PC Exchange version 2.1.1 or later.
After a disk image is selected, Disk Copy 6.1 or later will present a progress dialog for checksum verification and ask you for a floppy that is the same size as the disk image. You cannot, for example, use a 1.4 MB floppy to make an 800K volume.
When making floppies, Disk Copy 6.1 or later uses more memory that its default memory setting. If there is not free RAM available, Disk Copy will not be able to make the floppy and will present an error message. Either quit other running applications or increase Disk Copy’s Preferred memory size to 2048K.
