Optimize-AppXProvisionedPackages

  • Reference
Module:
DISM

Optimizes the total file size of provisioned packages on the image by replacing identical files with hard links.

Syntax

Optimize-AppXProvisionedPackages
        -Path <String>
        [-WindowsDirectory <String>]
        [-SystemDrive <String>]
        [-LogPath <String>]
        [-ScratchDirectory <String>]
        [-LogLevel <LogLevel>]
        [<CommonParameters>]

Description

Optimizes the total file size of provisioned packages on the image by replacing identical files with hard links.

When building an image, mount the disk image, add AppX packages, optimize provisioned packages, then dismount the disk image.

Once an image with provisioned AppX packages is online, Optimize-AppXProvisionedPackages won't be able to optimize provisioned AppX packages. If you take an image offline and add packages, only the packages that are provisioned after the image was brought offline are optimized.

Examples

Example 1: Optimize provisioned packages in an offline Windows image

PS> Optimize-AppXProvisionedPackages -Path ".\wim\image.wim"

This command optimizes the total file size of provisioned packages in the image named image.wim.

Parameters

-LogLevel

Specifies the maximum output level shown in the logs. The default log level is 3. The accepted values are as follows:

  • 1 = Errors only
  • 2 = Errors and warnings
  • 3 = Errors, warnings, and information
  • 4 = All of the information listed previously, plus debug output
Type:LogLevel
Aliases:LL
Accepted values:Errors, Warnings, WarningsInfo, Debug
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-LogPath

Specifies the full path and file name to log to. If not set, the default is %WINDIR%\Logs\Dism\dism.log. In Windows PE, the default directory is the RAMDISK scratch space which can be as low as 32 MB. The log file will automatically be archived. The archived log file will be saved with .bak appended to the file name and a new log file will be generated. Each time the log file is archived the .bak file will be overwritten. When using a network share that is not joined to a domain, use the net use command together with domain credentials to set access permissions before you set the log path for the DISM log.

Type:String
Aliases:LP
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-Online

Do not use. Optimize-AppXProvisionedPackages can't optimize provisioned AppX packages if the image is online.

Type:SwitchParameter
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Path

Specifies the full path to the root directory of the offline Windows image that you will service. If the directory named Windows is not a subdirectory of the root directory, WindowsDirectory must be specified.

Type:String
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-ScratchDirectory

Specifies a temporary directory that will be used when extracting files for use during servicing. The directory must exist locally. If not specified, the \Windows\%Temp% directory will be used, with a subdirectory name of a randomly generated hexadecimal value for each run of DISM. Items in the scratch directory are deleted after each operation. You should not use a network share location as a scratch directory to expand a package (.cab or .msu file) for installation. The directory used for extracting files for temporary usage during servicing should be a local directory.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-SystemDrive

Specifies the path to the location of the BootMgr files. This is necessary only when the BootMgr files are located on a partition other than the one that you are running the command from. Use -SystemDrive to service an installed Windows image from a Windows PE environment.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-WindowsDirectory

Specifies the path to the Windows directory relative to the image path. This cannot be the full path to the Windows directory; it should be a relative path. If not specified, the default is the Windows directory in the root of the offline image directory.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False
