What file extension do virtual disk files typically have?

The correct answer is .vdmk, which is the file extension associated with virtual disk files created by VMware. These files contain data that simulate a physical disk drive, allowing virtual machines to operate as if they have their own dedicated hard drives. The .vdmk file format supports features such as snapshots and disk cloning, making it essential for virtualization solutions.

This specific extension is recognized by virtualization software like VMware Workstation and VMware ESXi, enabling the software to read and manage the stored data effectively. In a broader context, variations of virtual disk files exist, such as .vdi for Oracle VirtualBox and .vhd/.vhdx for Microsoft Hyper-V, but .vdmk is unique to VMware, providing it with a distinct identity in the virtualization ecosystem.
