To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

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QCOW is an obsolete file format which has been superseded by QCOW2.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.
