How can you zip or unzip from the script using ONLY Windows' built-in capabilities?

To expand upon Steven Penny's PowerShell solution, you can incorporate it into a batch file by calling powershell.exe like this:

powershell.exe -nologo -noprofile -command "& { Add-Type -A 'System.IO.Compression.FileSystem'; [IO.Compression.ZipFile]::ExtractToDirectory('foo.zip', 'bar'); }"

As Ivan Shilo said, this won't work with PowerShell 2, it requires PowerShell 3 or greater and .NET Framework 4.

If you have Java installed, you can compress to a ZIP archive using the jar command:

jar -cMf targetArchive.zip sourceDirectory

c = Creates a new archive file.

M = Specifies that a manifest file should not be added to the archive.

f = Indicates target file name.

PowerShell 5.0

From Microsoft.PowerShell.Archive you can use:

• Compress-Archive
• Expand-Archive

E.g.:

• Create result.zip from the entire Test folder:

  Compress-Archive -Path C:\Test -DestinationPath C:\result
  

• Extract the content of result.zip in the specified Test folder:

  Expand-Archive -Path result.zip -DestinationPath C:\Test
