What is a .VMSS file?
A .VMSS file is a type of file used by VMware virtualization software to save the current state of a virtual machine (VM) when it is paused or suspended. This means that if you are using a virtual machine and decide to stop it temporarily without shutting it down completely, the software automatically creates a .VMSS file. This file holds all the information about the VM's current state, allowing you to resume exactly where you left off later.
The .VMSS file is particularly useful because it helps manage computer resources efficiently. When you suspend a VM, it stops using the system's resources (like CPU and memory), which frees up these resources for other tasks. This is beneficial when you are running multiple virtual machines on a single physical computer and want to switch between them without causing performance issues.
### Programs that can open .VMSS files: - **VMware Workstation**: This is a popular application used on Windows and Linux systems for operating system virtualization. It allows users to run multiple virtual machines. - **VMware Fusion**: This software is similar to VMware Workstation but is designed for Mac computers. It lets Mac users run virtual machines that can operate different operating systems like Windows or Linux alongside their macOS.
### Location of .VMSS files: When you suspend a virtual machine using VMware software, the .VMSS file is automatically saved within the virtual machine's main directory. For instance, on a Mac using VMware Fusion, this file is typically stored in a folder path like `Macintosh HD/Users/[username]/Virtual Machines`. The exact location might vary depending on your settings and the version of the software.
### Additional Information: When you resume the virtual machine, the VMware software reads the .VMSS file to restore the VM to its suspended state and then deletes the .VMSS file since it's no longer needed. This ensures that your storage is not filled with unnecessary files.
It's important to note that a .VMSS file is different from a snapshot file, which has extensions like .VMSN or .VMSD. While a .VMSS file represents a temporary state when a VM is paused, snapshot files are used to save a VM's state at a specific point in time intentionally, which can be reverted to later if needed.
In summary, .VMSS files are essential for efficiently managing and operating virtual machines using VMware software, allowing for smooth transitions between multiple VMs and conserving system resources.
