What is a .vmsd file?
File Extension Details
The VMSD file is a metadata file used by VMware virtualization software, specifically associated with VMware Workstation, VMware Player, and VMware ESXi. When a user creates a snapshot of a virtual machine to capture its state at a specific point in time, the virtualization software generates a VMSD file to store information about that snapshot. This file acts as a database or a log that tracks the relationship between different snapshots, the names assigned to them, the time they were created, and the specific virtual disk files (VMDKs) associated with each state. It is essentially a text-based configuration file that allows the hypervisor to manage the snapshot tree, ensuring that when a user reverts to a previous state, the system knows exactly which disk sectors and memory states to restore. Without the VMSD file, the virtualization software would lose track of the snapshot hierarchy, making it difficult or impossible to manage or delete snapshots correctly. While it is a critical component of the virtual machine's snapshot infrastructure, it does not contain the actual data or memory state of the virtual machine itself, which are stored in separate files like .vmsn or .vmem.
