　　vmx—虚拟机主配置文件，Linux为cfg。
　　vmxf—虚拟机组补充配置文件
　　nvram—虚拟机BIOS信息
　　vmdk—虚拟机硬盘文件，较大。（http://baike.baidu.com/view/1659126.htm）
　　
　　vmsd—虚拟机快照信息和元数据文件
　　vmsn—虚拟机快照状态文件，较大。
　　vmem—虚拟机运行时出现的页面文件，即虚拟机内存镜像，每个快照也对应一个该文件，较大。
　　
　　vmss—虚拟机挂机状态文件
　　
　　vmtm—虚拟机组数据
　　
　　log—虚拟机日志文件
　　
　　VMware快照

　　经我试验，一个虚拟机至少有vmx和vmdk两个文件组成。
　　

Extension	File Name	Description
.log	.log 　　or 　　vmware.log	This is the file that keeps a log of key VMware Workstation activity. 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.
.nvram	.nvram 　　or 　　nvram	This is the file that stores the state of the virtual machine's BIOS.
.vmdk	.vmdk	This is a virtual disk file, which stores the contents of the virtual machine's hard disk drive. 　　A virtual disk is made up of one or more .vmdk files. If you have specified that the virtual disk should be split into 2GB chunks, the number of .vmdk files depends on the size of the virtual disk. As data is added to a virtual disk, the .vmdk files grow in size, to a maximum of 2GB each. (If you specify that all space should be allocated when you create the disk, these files start at the maximum size and do not grow.) Almost all of a .vmdk file's content is the virtual machine's data, with a small portion allotted to virtual machine overhead. 　　If the virtual machine is connected directly to a physical disk, rather than to a virtual disk, the .vmdk file stores information about the partitions the virtual machine is allowed to access. 　　Earlier VMware products used the extension .dsk for virtual disk files.
	-.vmdk	This is a redo-log file, created automatically when a virtual machine has one or more snapshots. This file stores changes made to a virtual disk while the virtual machine is running. There may be more than one such file. The ### indicates a unique suffix added automatically by VMware Workstation to avoid duplicate file names.
.vmem	.vmem	The virtual machine's paging file, which backs up the guest main memory on the host file system. This file exists only when the virtual machine is running, or if the virtual machine has crashed.
		Each snapshot of a virtual machine that is powered on has an associated .vmem file, which contains the guest's main memory, saved as part of the snapshot.
.vmsd	.vmsd	This is a centralized file for storing information and metadata about snapshots.
.vmsn	-Snapshot.vmsn	This is the snapshot state file, which stores the running state of a virtual machine at the time you take that snapshot
	-Snapshot.vmsn	This is the file which stores the state of a snapshot
.vmss	.vmss	This is the suspended state file, which stores the state of a suspended virtual machine 　　.Some earlier VMware products used the extension .std for suspended state files
.vmtm	.vmtm	This is the configuration file containing team data.
.vmx	.vmx	This is the primary configuration file, which stores settings chosen in the New Virtual Machine Wizard or virtual machine settings editor. If you created the virtual machine under an earlier version of VMware Workstation on a Linux host, this file may have a .cfg extension
.vmxf	.vmxf	This is a supplemental configuration file for virtual machines that are in a team. Note that the .vmxf file remains if a virtual machine is removed from the team.
