What is QCOW2 file?

QCOW2 files are disk images used with virtual machines run by the QEMU application. They hold compressed data and can be mounted on various operating systems.

Additional information

QEMU is an open-source processor emulator used to launch different operating systems, test software, etc. When creating a virtual machine, users should mount a disk image which QEMU will use as a hard drive for the guest machine. QCOW2 files are saved in the second version of QEMU's Copy on Write disk image format.

One of the second version's benefits is better compression meaning that more disk space can be saved. This makes QCOW2 files ideal for use with virtual machines, as they take up less disk space and can be easily moved around. QCOW2 files can be opened and worked with using the QEMU application or other apps supporting the format. Some specific conversion tools can convert QCOW2 to other formats.
