qcow is a file format for disk image files used by QEMU, a hosted virtual machine monitor. [1] It stands for "QEMU Copy On Write" and uses a disk storage optimization strategy that delays allocation of storage until it is actually needed.
The Quick Emulator (QEMU) [3] is a free and open-source emulator that uses dynamic binary translation to emulate a computer's processor; that is, it translates the emulated binary codes to an equivalent binary format which is executed by the machine.

A disk image is a snapshot of a storage device's structure and data typically stored in one or more computer files on another storage device. [1] [2]Traditionally, disk images were bit-by-bit copies of every sector on a hard disk often created for digital forensic purposes, but it is now common to only copy allocated data to reduce storage space.
Disk Copy was used for creating and mounting disk image files whereas Disk Utility was used for formatting, partitioning, verifying, and repairing file structures. The ability to "zero" all data (multi-pass formatting) on a disk was not added until Mac OS X 10.2.3. [5] Further changes introduced in Mac OS X Tiger, specifically version 10.4.3 ...
Disk Copy was also the name of an Apple utility distributed with some of the earliest versions of the classic 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 ...
