WOZ File Extension
Apple II Disk Image – file format by John K. Morris
WOZ is a file extension for an Apple II Disk Image, a disk image format used to store and transfer data from an Apple II floppy disk. Developed by John K. Morris, it was the standard disk image format for the Apple II series of personal computers.
Definition and Structure:
A WOZ file, also known as an Apple II Disk Image, is a virtual representation of a physical floppy disk used on Apple II series computers. It encapsulates the disk’s contents, including the operating system, programs, and data, into a single archive file. WOZ files maintain the disk’s file system hierarchy, sector layout, and boot information, making them an accurate representation of the original disk.
Usage and Compatibility:
WOZ files are primarily used for preserving, archiving, and distributing vintage Apple II software and data. They allow enthusiasts to access and preserve historical programs, games, and documents. Additionally, WOZ files play a crucial role in emulating Apple II systems, as they provide the virtual disks necessary for running software on emulators. Compatibility-wise, WOZ files are only compatible with emulators or hardware that supports the Apple II disk format and operating system.
Opening WOZ Files on Windows
To open a WOZ file on Windows, you will need to download and install a compatible emulator or virtual machine. Some popular options include Basilisk II and SheepShaver. Once you have installed an emulator, you can mount the WOZ file as a virtual disk and access its contents. You may also be able to use a third-party application like WinImage to extract or convert the files within the WOZ image.
Opening WOZ Files on Mac
Opening a WOZ file on a Mac is simpler than on Windows. You can use the built-in Disk Utility application to mount the WOZ file as a virtual disk. Once mounted, you can access the files within the WOZ image as if it were a physical disk. You can also use third-party applications like iDisk or Disk Drill to extract or convert the files within the WOZ image.
What is a WOZ File?
A WOZ file is a disk image format used for Apple II computers. It was created by John K. Morris and is the most common disk image format for Apple II software. WOZ files contain an exact copy of the data on a physical Apple II floppy disk, including the operating system, programs, and data files.
Uses of WOZ Files
WOZ files are used to preserve and distribute Apple II software. They can be used to create backups of physical floppy disks, or to install software on an Apple II emulator. WOZ files can also be used to transfer software between different Apple II computers.
Technical Details of WOZ Files
WOZ files are stored in a compressed format that uses the Huffman algorithm. The compression ratio is typically around 2:1. WOZ files also contain a header that includes information about the disk image, such as the disk size and the operating system version.
