How to extract the install.wim file under Win8/8.1 through the dism command

Usually we extract files through third-party tools such as WinRAR. However, when using the install.wim file in Win8/8.1 system, there will be a file corruption error message. This is because these decompression tools do not support this format. At this time, we can use the dism command to extract the file.

The steps are as follows:

First, check the image version:

The image contains multiple versions, you need to confirm the version you need, my image path is "F: \\win8.1\\sources\\install.wim", execute the following command:

dism /get-wiminfo /wimfile:"F:\\win8.1\\sources\\install.wim"

As shown below, version 1 is Win8 Pro version 2 is Windows8 standard version, I am Win8 Pro natural selection 1.

Second, extract the Mirror:

I want to extract the install.wim file to c: \\ 111 folder for this purpose execute the command:

dism /Mount-wim /wimfile:"F:\\win8.1\\sources\\install.wim" /index:1 /mountdir:c:\\111

After the command is completed, open c:\\111 as shown After the extraction is complete, you can choose to copy the required files.

Third, unmount Image:

After the completion of the extracted files are no longer needed can be uninstalled before uninstalling turn off the Mirror folder, and then execute the command:

dism /Unmount-wim /MountDir:c:\\111 /discard

When the command is completed, c:\\111 will become an empty folder.

Through the above operation, we succeeded in extracting the install.wim file. In addition, we can also use the dism command to solve the redundancy update problem of the WinSxS folder.
