Whatﾕs new with ShrinkWrap 3.0 from Aladdin?
･ Added read/write/mount support for Appleﾕs NDIF (New Disk Image Format) image files.
･ Built-in DiskCopy compression builds NDIF compressed images more than three times as fast as DiskCopy 6.1.
･ New StuffIt compression saves about 30% more space and is still more than twice as fast as DiskCopy 6.1.
･ ShrinkWrap 3.0 image files and ShrinkWrap self-mounting image files now support 40-bit dynamic RSA-compatible encryption.
･ Now supports CRC-32 checksums, in addition to DiskCopy 4.2 checksums.
･ New self-mounting image files mount with a double-click and support mounting as unlocked volumes.
･ When mounted as RAM disks, image files now stay compressed and encrypted in RAM.
･ Added read/mount support for Toast CD-ROM Pro and CPS FastCopy compressed disk image files.
･ Added read/mount support for Windows Media Distribution Format (MDF) floppy disks with PC Exchange 2.0.7 and later.
･ Temporary files are no longer created on your hard drive to mount DART, Floppier and FastCopy image files.
･ Caches to the hard drive to minimize ejects during disk-to-disk duplication of large removable drives.
･ New option in Preferences scans disk images as theyﾕre mounted and auto-launches software installers.
･ The StuffIt Engine can now automatically BinHex any image files you create.
･ Batch operations can be conducted on collections of image files by simply selecting a folder or volume.
･ Floppy I/O is now fully asynchronous, so you can continue to be productive while ShrinkWrap works in the background.
Why use ShrinkWrap?
1. To create disk image files quickly and efficiently:
To create disk image files using ShrinkWrap, just drag and drop your disk icons onto the ShrinkWrap icon. In Batch Floppy Mode, you can continue to feed in floppy disks until your entire archive has been converted into image files without ever needing to touch the mouse or keyboard.
To convert your image files back to disk, just select the image files or a folder containing the image files, hold down the Command key and drag the icons onto the ShrinkWrap icon. You will be prompted to insert a disk as each image is written back to floppy disk. In Batch Floppy Mode, multiple copies of each image file may be made. Just select Stop when youﾕve made enough copies of each image.
2. To provide a convenient and reliable means of mounting disk image files on the desktop:
Like Apple's MountImage control panel, ShrinkWrap will mount image files on the desktop that to the system will appear identical to the original floppy disks. However, since ShrinkWrap is an application, it will never cause INIT conflicts and will never require any memory until it's actually run. To mount image files, simply drag and drop the image file icons onto the ShrinkWrap icon. Image files can be mounted as unlocked disks by holding down the Shift key during launch and even loaded into free memory to get the performance of a RAM disk just by setting an option in preferences.
3. To seamlessly handle disk image files in their archived form:
For years ShrinkWrap has automatically compressed and decompressed archived disk image files on the fly with Aladdin's StuffIt Engine. However, in version 3.0 you can save image files directly as compressed and/or encrypted image files. Later you can mount these images without needing to wait for them to be first processed by the StuffIt Engine. Decompression and decryption occurs at the driver level behind the scenes, achieving compression ratios as good as the StuffIt Engine and performance that is much faster than mounting old uncompressed DiskCopy files. You can even save ShrinkWrap images as self-mounting applications, which mount themselves with a simple double-click.
4. To provide a freely distributable alternative to Apple's DiskCopy, DART, Disk Image Mounter and MountImage:
DART, Disk Image Mounter and MountImage cannot yet legally be licensed for redistribution. Apple Computer, Inc. may at some time decide to license these utilities, but until that time, you may not legally redistribute it once you receive a copy from an authorized Apple source. DiskCopy is available for licensing, but at an often prohibitive cost of $5000 per year.
INSTALLATION
Install ShrinkWrap by simply double-clicking the file named ﾒShrinkWrap 3.0 Installerﾓ. A 15-day trial version of ShrinkWrap will be copied to your hard drive. When you choose to register ShrinkWrap, you can enter your registration number to disable the time limit.
<<Note: When re-installing immediately after the initial install via the "re-install" button a message reading "Installation was unsuccessfull" may appear. The installation will indeed be successfull.>>
In order to automatically compress and decompress archived disk images on the fly, youﾕll need a copy of the StuffIt Engine. Ideally, you will already have the StuffIt Engine installed in your Extensions folder. If not, you should obtain either DropStuff with Expander Enhancer or StuffIt Deluxe. DropStuff is available from our Web site at <http://www.aladdinsys.com>. Both of the these products contain the StuffIt Engine.
SYSTEM REQUIREMENTS
ShrinkWrap is a Mac OS application for Macintosh and Power Macintosh, requiring System 7 and later. It contains both 68K and PowerPC native code, is AppleEvent aware, 32-bit clean, AV, ﾕ040 cache and virtual memory compatible. Although a Macintosh SE or better is required for full functionality, the Mac Plus can still use ShrinkWrap to mount, convert and verify disk image files. The Component Manager, available with QuickTime 1.5 or System 7.1 or later, is required to handle compressed or encrypted disk images.

INTRODUCTION
Why do we need to deal with disk images?
Although there is some similarity between disks duplicated from disk images and disks copied by dragging icons, the results are not identical. Disks created from image files are exact duplicates, including the exact icon placement, appearance of all windows, and the correct name of the disk. In addition, with disk images you have the added assurance that all the files have been duplicated correctly and completely. More importantly, Apple's Installer may not recognize disks copied by dragging icons, even if they appear identical in every way.
Some convenient uses for disk images:
1. Backing up your original floppy disks to removable media:
A Magneto-Optical, Iomega, Bernoulli, SyQuest or CD-R drive can serve as an excellent means to back up your software. When disk image files are stored in compressed form, they are space efficient but still easily accessible with ShrinkWrap. Just drag the compressed image onto the ShrinkWrap icon and the file will be immediately mounted on the desktop.
2. Installing Apple's System Updates and System Software Extensions:
Since most of Apple's System Software, System Updates and System Extensions (CD-ROM Setup, PlainTalk, printer drivers, etc.) are distributed online in image file format, it's convenient to be able to mount the images and run the Installer without ever having to copy the images back to floppy disk.
3. Distributing multiple disk images on floppies:
Using compressed ShrinkWrap disk image files, you can achieve adequate compression to store three or more 800K disk images on a 1.44 MB HD floppy.
4. Mounting floppies on Macs without a SuperDrive:
For Macs not equipped with a SuperDrive, ShrinkWrap provides a cost-effective and convenient means of accessing data stored on HD floppy disks.
5. Creating ﾒinstantﾓ RAM disks:
Placing a ShrinkWrap disk image file in your Startup Items folder will make it always available from startup, just like a RAM disk. However, when youﾕre done with the ShrinkWrap RAM disk and need to free up the memory, just drag the mounted image to the trash. No need to restart. Many users find ShrinkWrap temporary RAM disks to be a fast and more space efficient place to store their Web browserﾕs cache files.
6. Distributing software collections and archives on CD-ROM:
ShrinkWrap provides a convenient and economical means for your customers to obtain copies of their software on floppy media even if your product is now being distributed exclusively on CD-ROM. With ShrinkWrap's extensive AppleScript support and StuffIt InstallerMaker integration, you can even offer users the ability to create floppies directly from your product's installer.
7. Verifying the integrity of development builds:
ShrinkWrap provides both DiskCopy 4.2 and CRC-32 checksums for use in confirming the data integrity of floppies or CD-ROMﾕs when it's absolutely vital that you ensure an exact copy was made.
