Which file from the virtual machine directory contains the suspended virtual machine's memory contents?

The file that contains the suspended virtual machine's memory contents is the one with the extension .vmss. When a virtual machine is suspended, its current state, including the contents of its memory, is saved to this file. This allows the virtual machine to preserve its execution context and state so that it can be resumed later exactly where it left off.

In a virtual environment, the .vmss file serves a specific purpose related to memory management during suspension, ensuring that all in-memory data is stored securely. When the virtual machine is resumed, the system reads this file to restore the state, allowing the user to continue working without any loss of data or progress.

In contrast, the other file types serve different functions. For instance, the .vmdk file is used for storing the virtual machine's disk data, .log files are utilized for logging events or errors related to the virtual machine's operations, and .vmx files contain the configuration settings for the virtual machine. While all these files are critical for the functioning of a virtual machine, the .vmss file specifically handles the storage of memory contents during a suspension event.
