Recovering Data Of a VMware Virtual Machine
Read about recovering a deleted VMware Workstation virtual machine or the contents of a virtual machine disk, and the built-in virtual machine tools or third-party utilities for recovery. VMware Workstation and VMware Player are virtualization software meant to enable simultaneous work of several operating systems on a single physical computer. In this case, one of the operating systems works as a virual machine based on VMware.
VMware is one of the most stable and safest platform for virtualization that allows more flexibilty and effectiveness for many IT specialists and software developers.

It means that VMware Workstation is a virtual operating system that works inside the operating system of your computer. All files of this operating system (both system files and user files) are stored on the computer’s hard disk, and by default they are located in this folder:
Most often, users do not need to know the names and location of VMware virtual machine files. The application itself manages its files. Yet there can be situations when such knowledge is necessary, for example, if a virtual machine needs to be recovered after it was lost, or when you need to recover files deleted from such machine and so on.
As you can see from the screenshot above, a virtual machine folder consists of a certain set of files. VMware creates such separate folder for every virtual machine and gives it the name of the virtual machine which was given to it by the user, when such virtual operating system was installed.
Main files of a virtual machine have the following extensions:
- *.log – VMware Workstation key activity log. It is used to eliminate errors if they emerge
- *.nvram – the file containing conditions and BIOS settings of the virtual machine
- *.vmdk – a virtual disk file where contents of the virtual machine hard disk are stored
Note. Depending on VMware Workstation settings, the virtual machine disk can consist of one or several *.vmdk files. When files are added to such disk, its size becomes bigger.
- *.vmem – the virtual machine paging file. It is created and can be seen only when the virtual machine is in use.
- *.vmsd – the file containing current snapshot parameters
- *.vmsn – snapshot condition file which stores the current condition of the virtual machine when it is used
- *.vmss – a condition file of the suspended virtual machine
- *.vmtm – the configuration file, one of parameter files of the virtual machine
- *.vmx – the main configuration file where all virtual machine parameters are stored
- *.vmxf – an additional configuration file.
Note. The files we have described above are the main files of a virtual machine. In the folder of the virtual machine there can be other files and folders as well, including those which are only shown when the machine is running.
Accidental deletion, formatting of the hard disk or damaging the file system – all of these misfortunes can result in a loss of data. As a rule, however, virtualization software does not provide built-in recovery options. In this connection, the issue of recovering virtual machine data becomes quite complicated for the users.
In the previous paragraph, we have described the main file types that a virtual machine consists of, and where all of its data is stored. By recovering them and opening in VMware the main configuration file, where all virtual machine parameters are stored, any user can restore a lost virtual machine..
To recover a deleted virtual machine, do the following:
Using this application, go to the folder from where the virtual machine was lost or deleted
Move all files of such folder to the Recovery list and recover them
Open the .vmx file of the recovered virtual machine with the use of VMware Workstation
Start the virtual machine
As we have already said, all files stored in virtual machine disks are located in .vmdk files of the virtual disk. Hetman Partition Recovery, the program for hard disk data recovery has the function of mounting virtual disks and recovering data from such disks.
If for some reason your virtual machine is no longer working, and there are important files on its disks, this data can be recovered. To do it:
Run Hetman Partition Recovery and mount the virtual machine disk. If there are several of them, you can mount them all at once or one by one.
Note. To mount a virtual disk with the help of Hetman Partition Recovery, click on Mount Disk in the quick access menu of the program. As a result, the window of choosing a virtual disk will open. In the right lower corner, specify the file type as «All files (*.*),» go to the folder containing the virtual machine and choose the required .vmdk file.
As you do that, the section «Mounted Disks» containing the list of mounted virtual disks will appear in the window, where all disks found by the application are shown. If you mount several disks, you will see the entire disk list there.
Scan the disk with the application by double-clicking on the disk in the disk manager.
After the analysis, the application will show the directory tree of the scanned disk. Find and recover the required files.
As a result of experiments we have established that files deleted or lost inside a virtual machine cannot be recovered.
Though VMware Workstation is a virtual machine, it can contain real data. Because of that, loss of access to the virtual machine or its deletion can become an unpleasant surprise, while an opportunity to recover it will keep user data safe from possible irreparable loss.
