What is WIM file?

WIM (Windows Imaging Format) file is a disk image file. The format was introduced by Microsoft along with Windows Vista operating system.

WIM file capabilities

WIM image files are usd by Windows Server 2008 and Windows Vista during the system installation process – they were originally designed for that specific purpose. WIM file allows single disk image to be deployed on multiple operating systems. They enable users to manage various system elements, for example, updates, drivers, and components without the need for running the system image.

A single WIM can hold several disk images, which can be then mounted in Windows as separate volumes. An Wim file can be run as separate machine if it is a system disk image.

Compression and SIS technology

WIM file format is file-based, which means it can utilize Single-Instance Storage (SIS) technology to store duplicate files only once. WIM image file offers 3 compression levels: LZX (maximum compression), XPRESS (maximum speed).

WIM image file structure

  • „WIM Header” – describes file contents and metadata,
  • „File Resources” – source files and other data packages,
  • „Metadata Resource” – contains information regarding other files,
  • „Lookup Table” – holds information about location of resource files,
  • „XML Data” – additional information about the disc image,
  • „Integrity Table” – information regarding file security.

What else may cause problems?

There can be more reasons which determine that you are not able to open the WIM file (apart from the lack of the proper application installed).

First - the WIM file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the WIM file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the WIM file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the WIM file has not been completed and it cannot be opened properly).
