What is a VMSN file?

VMSN files mostly belong to VMware Workstation. VMSN files store a virtual machine's snapshot state used by VMware Workstation.
This file records the status of the VM at a specific moment. It holds the memory contents and configuration details needed to restore the VM later.
Key points as outlined by FilExt.com include:

Snapshot State: Captures the live state of the system at the time the snapshot is taken.

Restoration Tool: Enables you to revert the virtual machine to this exact state.

File Integration: Works alongside other VM files such as configuration (.vmx) and disk (.vmdk) files.
