VMware virtual machine file (suffix) detailed

The virtual machine's file management is performed by VMware Workstation, a virtual machine typically stored in a series of files in a host, typically in the directory created by workstation for the virtual machine.
The extensions for these key files are listed here. In these examples,,<vmname> represents your virtual machine name.


. log
<VM Name>.log or Vmware.log
This document records how VMware Workstation operates on virtual machines. These files are very useful for us to troubleshoot when you encounter problems. This file and the virtual machine's configuration file (. vmx) are stored in a directory.

. nvram
<VM Name>.nvram or NVRAM
This is a file that stores BIOS status information for a virtual machine.

. vmdk
<vmname>.vmdk
This is a virtual disk file that stores the contents of the virtual machine's hard drive.
A virtual machine can consist of one or several virtual disk files. If you have specifically specified a virtual disk as a separate file per 2GB, the size of the virtual disk determines the number of virtual disk files. As data is written to the virtual disk, the virtual disk files become larger until these files are 2GB. (If you have allocated all the space when you created the virtual disk, the files will have the largest size and no longer become larger at the beginning). Almost all of the virtual disk file content about the disk data in the virtual machine, only a small part of the virtual machine partition information.

If a virtual machine is connected directly to a physical hard disk rather than a virtual disk, the virtual disk file holds the partition information that the virtual machine can access.

Earlier versions of VMware products use the. DSK extension to represent virtual disk files.

<disk NAME>-<###>.VMDK
This is the name of the file, which is created automatically when the virtual machine has one or more snapshots. When the virtual runtime is running, this file is used to store the contents of the virtual disk changes. There may be multiple files for this. The virtual machine is #这种文件名不重复出现的后缀的命名方式以避免文件重名 by adding # #.

.vmem 
<UUID>.VMEM&NBSP;
The virtual machine paging file, which is used to back up the main memory information that the client saves on the host. This file exists only when the virtual runtime is running or after a crash.
<snapshot name and number> 
The snapshot that is created for each virtual machine is a. vmem file that contains the resident memory information for the client, which is part of the snapshot.

. vmsd
<VM NAME>.VMSD
This is a file that centrally stores information and metadata about the snapshot. In its directory, it is possible that some other files exist only when the virtual runtime is running. (And it won't go away)

. vmsn
<vmname>-snapshot.vmsn
This is a snapshot status information file that records the state information of the virtual machine when you set up the snapshot
<vmname>-snapshot<###>.vmsn
This is also the file that stores the snapshot status information.

. VMSs
<vmname>.vmss
This is a file that stores the suspended state information for a virtual machine. Some earlier versions of VM products use. Std to represent this file.

. Vmtm
<vmname>.vmtm
This is the configuration file that contains the virtual group data.

. vmx
<vmname>.vmx
This is an initial configuration file that stores some of the settings for virtual machines created by the Virtual Machine Wizard or the virtual Machine editor. If you are using a VM virtual machine under Linux, the file extension is. cfg.

. VMXF
<vmname>.vmxf
This file is a supplemental configuration file in the virtual machine group. Note that when the virtual group is removed, the file will remain.

Some files in the directory exist only when the virtual runtime is running.
