unzip it with good pressure today. Windows 8.1 Install.wim file, actually prompt file corruption, changed 7Z still so; the file is actually good. It's just that the software doesn't support it at the moment, but it's OK to do it manually with the DISM command.
First, check the image version:
The image contains more than one version, you need to confirm the version you need, my mirror path is "F:\win8.1\sources\install.wim", execute the following command
Dism/get-wiminfo/wimfile: "F:\win8.1\sources\install.wim"
Version 1 is Win8 Pro version 2 is WINDOWS8 Standard Edition, I am WIN8 Pro Natural Selection 1
Second, unzip the 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:\win8.1\sources\install.wim"/index:1/mountdir:c:\111
After the command is completed, open c:\111 to extract the files you want to copy.
Third, unmount the image:
After you finish extracting the files, you no longer need to be able to uninstall, close the Mirror 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.
