What is a .vmsn file?
File Extension Details
The vmsn file is a proprietary file format used by VMware virtualization software, specifically VMware Workstation, VMware Player, and VMware Fusion. It serves as a snapshot state file that captures the exact state of a virtual machine at a specific point in time. When a user creates a snapshot of a virtual machine, the vmsn file stores the configuration, the state of the virtual hardware, and, depending on the settings, the memory state of the guest operating system. This allows the user to revert the virtual machine to that exact state later, effectively 'undoing' any changes made to the system, software, or data after the snapshot was taken. Because it often includes the contents of the virtual machine's RAM, these files can grow quite large in size. They are essential for developers and system administrators who need to test software installations or system configurations in a safe, repeatable environment where they can quickly roll back to a clean state if errors occur.
