.vud File Extension

Developer: Microsoft
File type: Virtual Machine Undo Drive File
You're here because you have a file that has a file extension ending in .vud. Files with the file extension .vud can only be launched by certain applications. It's possible that .vud files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .vud file?

The .vud file extension is mainly associated with Windows Virtual PC, a program that allows users to run virtual machines on Windows. Files with this extension are known as Virtual Machine Undo Drive File because they are usually used to save whatever changes made to the virtual disk of the virtual machine. These files allow the tracking of created, edited and deleted files using the program. They are called “undo” files because they only exist if there is an enabled “undo disk” as well as because there are actually two “undo” options that these files can provide to the users. One is the discard undo tasks and the commit undo tasks. The discard undo allows users to delete whatever changes made to the virtual hard drive and restore the data last loaded; while the commit undo task allows users to permanently apply the changes that have been made to the virtual hard drive.

how to open a .vud file?

Launch a .vud file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .vud file will open it.

In this case, when you try to open a .vud file, you can tell Windows which application is the correct one for that file. From then on, opening a  .vud file will open the correct application.

applications that open a .vud file

Microsoft Windows Virtual PC

Microsoft Windows Virtual PC

Windows Virtual PC and server applications are integrated primarily with the .vsv file extension, and the files that are made with these applications are saved and bear the .vsv format. These files are believed to be the Virtual Machine Saved State File due to the state of its virtual machine memory that uses the said file extension and is called the VSV file. Virtual Machine snapshots are able to be saved and be reverted it to its original format with the use of these files. VSV files cannot be accessed directly since it is referenced by the VMC files. Windows Virtual PC virtualizes a basic PC and its related hardware. Supported Windows operating systems can work inside a Virtual PC, however, the other operating systems such as Linux may work, but are not officially supported, and Microsoft does not give the necessary Virtual Machine Additions, which include essential drivers for Linux.

a word of warning

Be careful not to rename the extension on .vud files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .vud. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
