Apple software list & details
Disk Copy
Developer / company: Apple
Disk Copy was the default utility for handling disk images in System 7 through Mac OS X 10.2 (Usable in System Software 6 as well). In later versions of Mac OS X it has been replaced by DiskImageMounter for mounting the images and Disk Utility for creating them.
Although the last official public release of Disk Copy for Mac OS 9 was version 6.3.3, there was to be a version 6.5 that supported the newer DMG image format introduced with Mac OS X. But because Apple had stopped support for OS 9 already, support for the old OS was eventually removed in favour of OS X. As such the OS 9 version of 6.5 only ever made it to beta 13 before development on it stopped. There was also a developer version 6.4 that 6.5 was based on and had most of the same functionality, but as a developer version it was never released.
Disk Copy was also the name of an Apple utility distributed with some of the earliest version of the Mac OS. In order to copy 400K floppy disks using as few disk swaps as possible on a machine with only 128K of RAM, the original Disk Copy used the screen buffer to store binary data from the disk being copied; as a result, the screen (other than a small area at the bottom displaying the GUI) filled with noise while copying was in progress.
The Disk Copy software seems to be old or discontinued.

The list of extensions used or otherwise associated with the application may not be complete, because many common file extensions on our website, such as jpg (pictures) or txt (text files), can be opened by a large number of applications, or are too general file format. However most, if not all directly associated file extensions should be listed with its appropriate program. Although its likely, that some file extensions may be missing from the list of associated file extensions with the application, yet they can be opened, be part of, or otherwise be associated with the program.
