Let’s look at what files make a virtual machine. When you create a virtual machine, ESX automatically creates certain files that are associated with the new virtual machine. Let’s briefly discuss some of the files that compose the virtual machine content folder and what they do: .vmx is the virtual machine configuration. This is the primary configuration file, which stores settings chosen in the New Virtual Machine Wizard or virtual machine settings editor. .vmdk is an ASCII format, which stores the contents of the virtual machine's hard disk drive. There could be one or more virtual disk files. -flat.vmdk is single preallocated disk file that contains the data. .vswp are the swap files and are on a per-virtual-machine basis. .nvram is a non-volatile RAM that stores virtual machine BIOS information. .vmem is the virtual machine memory mapped to a file. .vmss is the virtual machine suspend state file, which stores the state of a suspended virtual machine. .vmsd is a centralized file for storing information and metadata about snapshots. .vmsn is the snapshot state file, which stores the running state of a virtual machine at the time you take the snapshot. .log are the virtual machine log files. This file can be useful in troubleshooting if you encounter problems. This file is stored in the directory that holds the configuration (.vmx) file of the virtual machine. A virtual machine is stored as a set of files and usually reside in a folder or subdirectory that is created by ESX for this virtual machine.
