A detailed explanation of the files in the VMware Virtual machine folder

File management for virtual machines is performed by VMware Workstation.

A virtual machine is typically stored as a series of files in a host,

These files are typically in the directory created by workstation for the virtual machine.

These key files and their extensions are listed here.

In the following illustration example,,<vmname> represents the name of the virtual machine created.

--------------------------------------------------------------------

. log files

File type Description: Text file

<vmname>.log or Vmware.log

This document records the operation of VMware Workstation on virtual machine debugging.

These files are useful for us to troubleshoot when problems are encountered.

--------------------------------------------------------------------

. nvram file

File type description: VMware virtual machine BIOS

<vmname>.nvram

This file stores the BIOS status information for the virtual machine.

--------------------------------------------------------------------

. vmx file

File type description: VMware virtual machine configuration

<vmname>.vmx

The file is a configuration file for a virtual machine that stores all the configuration of the virtual machine based on the Virtual Machine Wizard or the virtual Machine editor.

Sometimes it is necessary to manually change the configuration file to achieve changes to the hardware of the virtual machine. You can edit it using a text editor.

If the host is Linux, using a VM virtual machine, the extension of this profile is. cfg.

--------------------------------------------------------------------

. vmdk file

File type description: VMware Virtual Disk File

<VMNAME>.VMDK OR<VMNAME>-S###.VMDK

This is the disk file for the virtual machine, which stores the information in the virtual machine's hard drive.

A single virtual machine can consist of one or more virtual disk files.

If you specify a virtual machine disk file as a single file when you create a new virtual computer, only one <VMNAME>.VMDK file will be created

This file includes the virtual machine disk partition information, as well as all the data for the virtual machine disk.

As data is written to the virtual disk, the virtual disk file becomes larger, but only this one disk file is always available.

If you specify that a single disk file is created for each 2GB when you create a new virtual machine, the total size of the virtual disk determines the number of virtual disk files.

The system creates a <VMNAME>.VMDK file and multiple <vmname>-s###.vmdk files (s## #为磁盘文件编号),

Where the <VMNAME>.VMDK file contains only disk partition information, multiple <VMNAME>-S###.VMDK files store disk data information.

As the data is written to a virtual disk file, the Vdisk file becomes larger until the file size is 2GB.

The new data is then written to the other s## #编号的磁盘文件中.

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 initial time.

If a virtual machine uses a physical hard disk instead of 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.

<vmname>-<######>.vmdk

When a virtual machine has one or more snapshots, the file is automatically created.

This file records the disk data content of all the virtual machines when a snapshot is created.

##### #为数字编号, automatically increases depending on the number of snapshots.

--------------------------------------------------------------------

. vmsd file

File type description: VMware snapshot metadata

<vmname>.vmsd

This file stores information and metadata about the snapshot of the virtual machine.

--------------------------------------------------------------------

. vmsn file

File type description: VMware virtual machine Snapshot

<vmname>-snapshot<##>.vmsn

When a virtual machine establishes a snapshot, the file is automatically created. There are several snapshots that will have several such files.

This is the status information file for the virtual machine snapshot, which records the status information of the virtual machine when the snapshot is established.

# #为数字编号, the number of snapshots increases automatically.

--------------------------------------------------------------------

. vmem file

Description of the file type: VMEM

<vmname>-<uuid>.vmem

The file is a virtual machine memory paging file that backs up memory information that is running in the client.

This file exists only when the virtual runtime is running or after a crash.

--------------------------------------------------------------------

. vmss File

File type description: VMware suspended virtual machine state

<vmname>.vmss

This file is used to store information about the virtual machine in the suspended state.

Some earlier versions of VM products use. Std to represent this file.

--------------------------------------------------------------------

. vmtm file

File type description: VMware team Configuration

<vmname>.vmtm

The file is the configuration file for the virtual Group team. It usually exists in the folder of the virtual Group team.

--------------------------------------------------------------------

. vmxf file

File type description: VMware team member

<vmname>.vmxf

This file is the secondary profile for the virtual machine in the virtual group team.

This file also exists when a virtual machine is removed from the virtual group team.

--------------------------------------------------------------------

The file types described above do not necessarily exist in the virtual machine directory.

Some of these files exist only when the virtual runtime is running.
