The QCOW file type is primarily associated with 'QEMU' by Fabrice Bellard.
QCOW is an obsolete file format which has been superseded by QCOW2. This file belongs to QEMU; an open-source VM (Virtualization Machine) and emulator software solution and stores image files.
Virtualization has made great strides in becoming a much coveted solution for running multiple environments on one physical machine. The benefits are multi-layered ranging from a more flexible deployment and maintenance system to reduced costs in both energy and ongoing expenses.
