What is a .vmss file?
File Extension Details
The VMSS file extension stands for VMware Suspended State. It is a proprietary file format created and used by VMware virtualization software, including VMware Workstation, VMware Fusion, and VMware ESXi. When a user chooses to suspend a running virtual machine rather than shutting it down completely, the virtualization software saves the current state of the virtual machine's virtual CPU, registers, and device configurations into a .vmss file. This file works in tandem with a .vmem file, which contains the virtual machine's active RAM contents. Together, these files allow the virtual machine to be paused and later resumed instantly at the exact point where the user left off, preserving all open applications, documents, and system states. Because .vmss files contain active system state data, they are typically large and should not be manually edited or deleted while the virtual machine is suspended, as doing so will corrupt the suspended state and force a cold reboot of the guest operating system.
