The MDK format includes multiple differing subformats, some of which store metadata in an external descriptor file, while others embed it with the main data in a single file. The descriptor specifies a series of one or more extents that typically refer to a file or device that holds the actual data, unless for example they are of type ZERO, which emulates a zero-filled extent.

Each extent can be marked either RAW, ONLY, or ACCESS to signify that the virtual machine should have respectively read/write, read-only, or no access to that part of the disk. Zeroedthick: Blocks are allocated during initial provisioning but are not zeroed until first access.

The Defile extension refers to “Virtual Machine Disk”. It’s an open file format provided by VMware, mostly used for services for cloud computing and virtualization.

Defile extension is meant for server operations and is highly compatible with Core’s WinZip. Launch WinZip from your start menu or Desktop shortcut.

Or multi-select only the files or folders you want to open by holding the CTRL key and left-clicking on them. Choose the destination folder to place the extracting files and click “Unzip” button.

We designed WinZip to open and extract from the widest range of file formats, including all the following: Get WinZip now to open your Defile (s), then enjoy all that the world's most popular compression utility has to offer, including the easiest and most practical file compression, encryption, packaging, file management and data backup capabilities.

MDK stands for ‘Virtual Machine Descriptor File ’. It is basically a Virtual Hard Disk which is used to store one or more Virtual Files, and it can only be accessed as a physical hard disk with VMware Software.

It was developed by ‘VMware Software’ for its various Virtual Products and the earlier versions of VMware software used the .DSK extension for virtual disk files. Even being developed by VMware software, there are instances when your files get corrupted which leads to inaccessible data.

But before we work on getting back that damaged data, let’s first go through the reasons for corruption of your files: If the descriptor gets corrupted then there are great chances that your file might not open.

Another reason is missing descriptor files for delta disk. This online application is one of the best available tools to view and open Defile in Windows 10, 8, 7, XP and other versions.

Plus the best part of this tool is that it provides users a free demo version which lets you evaluate the complete features that the software is providing. Note: The application not only allows you to view the data but also help users to recover them after corruption.

Now, select corrupt MDK files which you want to repair and then click on Open. All the detailed information of selected file like file format version, size of hard disk, head, cylinder, sector per track will appear on the screen.

Choose any recovery mode out of three options “Standard”, “Advanced” and “Deep” as per your corruption type Then click on Next to begin. Now, the recovery process will start which will recover the corrupt data from your MDK files.

After completion of process, click on OK and proceed forward to save the recovered file The software will now show you the preview of data in a tree-structured format. Saving process is completed, and now you can access your recovered file.

The disk file is essentially a complete and independent virtual machine. A disk file with the MDK extension is a virtual machine using VMware virtualization products or other platforms that support MDK files such as Sun VM, EMU, or VirtualBox.

We know of 2 different uses of the Defile type, one of them being (part of a) VMware 3 Virtual Disk. The Defile extension indicates to your device which app can open the file.

However, different apps may use the same file extension for different types of data. In this case, look through both formats to make sure you find the best suited MDK viewer.

Through our analysis of MDK files, we know that one use of the format is (part of a) VMware 3 Virtual Disk. Vmdkfile extension are Virtual Machine Disk Files.

These files store the contents of a “virtual” hard disk that has been created by the VMware virtual hard drive software. VMWare is used as a “Software PC”, allowing you to install e.g. Windows into a virtual PC, storing the operating system and all apps you install in a .

VMWare is needed to run the operating system that is installed within the Defile, but various other tools can extract data from the file. We have not verified any online services that we know for certain can work with MDK -files.

Virtual machine file management is performed by VMware Workstation. If the behind the scenes file structure is not interesting to you, skip this section.

This is the file that keeps a log of key VMware Workstation activity. This is the file that stores the state of the virtual machine's BIOS.

Vmdkfile stores information about the partitions the virtual machine is allowed to access. Earlier VMware products used the extension .DSK for virtual disk files.

The ### indicates a unique suffix added automatically by VMware Workstation to avoid duplicate file names. This is a centralized file for storing information and metadata about snapshots.

Note that the .IMF file remains if a virtual machine is removed from the team. There can be other files in the directory, some of which are present only while a virtual machine is running.

You can import MDK files into a virtual machine when you set it up or after the fact. People use them to host multiple servers on the same physical hardware, to run other operating systems for particular software and to run programs isolated from their main systems for security's sake.

Other popular virtualization software includes VirtualBox and the Parallels' system used for running Windows on a Mac computer. Then, use this procedure to add the existing Defile to the virtual machine and spin it up to start the operating system.

VirtualBox supports virtual disk images created by other virtualization programs, including MDK files, Microsoft's VHD format and some versions of the format used by Parallels. When you set up a virtual machine in VirtualBox, you'll be given the option to choose an existing disk image file, which could be a Defile, to use as the device's emulated hard drive.

You can also clone a virtual disk in VirtualBox if you want to make a copy of it so the original stays unmodified. A Defile stores complete content of the virtual machine on a hard disk drive and its maximum size has been extended unto 62 TB.

The database file can go through the undesirable corruption phase owing to factors like abrupt shutdown of Virtual Machine, interrupted/fluctuated power supply, virus intrusions, anti-virus or other software programs inflections, forced shutdown of system, and others. A Virtual Machine User can assume that the Defile is corrupt in the following situations.

To recover data from corrupt or damaged MDK files manually, we have two options mainly. Both these manual solutions are tricky and technical ones, so users have to perform it carefully in order to get the desired results.

Repairing Corrupt/Damaged MDK files via Command Prompt Type cmd in the Search box at the Start menu on your system. Then right-click on Command Prompt application from the search result and click on Run as Administrator option.

Now, move on to a healthy Virtual Machine and here, create a copy of the pointer file from there. Note: If users are getting errors related to corrupted .VME and .VMS files and system cannot load a memory page.

Now, users can restart or reboot the Virtual Machine system to restore the MDK data in healthy form. The main drawbacks of these manual solutions which can hold on the users to repair their corrupted MDK files is difficulty in attaining the required sizes of Cylinders, Heads, Fields for modification of original MDK files need for Machine rebooting.

There is nothing to lose with that tool rather users can get back to accessing the original file and its data without any integrity and structure interference. End Words The Defile corruption can occur due to different reasons which may go to the limit of affecting the Virtual Machine Server slowing it down or completely shut down.

Some manual processes can be tried but all in vain if the actual settings are unknown and the user has no technical expertise.
