win8/8.1 the Install.wim file by using the DISM command

Usually we extract files through Third-party tools, such as WinRAR. However, when using the Install.wim file in the win8/8.1 system, the file corruption error is prompted, because these decompression tools do not support this format, then we can extract the file through the DISM command.

The steps are as follows:

First, check the mirror version:

The mirror contains more than one version, you need to confirm the version you want, my mirror path is "F:win8.1sourcesinstall.wim", then execute the following command:

Dism/get-wiminfo/wimfile: "F:win8.1sourcesinstall.wim"

As the following illustration shows, version 1 is WIN8 Pro version 2 is WINDOWS8 Standard Edition, I am WIN8 Pro Natural selection 1.

Second, decompression Image:

I want to extract the Install.wim file into the c:111 folder and execute the command for this:

Dism/mount-wim/wimfile: "F:win8.1sourcesinstall.wim"/index:1/mountdir:c:111

When the command is complete, open c:111 as shown in the diagram, you can choose to copy the required files.

Third, uninstall the Mirror:

After you finish extracting files, you no longer need to uninstall, close the mirrored folder before uninstalling, and then execute the command:

Dism/unmount-wim/mountdir:c:111/discard

When the command is complete, the c:111 becomes an empty folder.

Through the above operation, we have successfully extracted the Install.wim file. In addition, we can use the DISM command to resolve the redundant update of the WinSxS folder.
