DISM Image Management Command-Line Options

Published: April 1, 2014

Updated: April 1, 2014

Applies To: Windows 8, Windows 8.1, Windows Server 2012, Windows Server 2012 R2

Deployment Image Servicing and Management (DISM.exe) mounts a Windows image (.wim) file or virtual hard disk (.vhd or .vhdx) for servicing. You can also use the DISM image management command to list the image index numbers, to verify the architecture for the image that you are mounting, append an image, apply an image, capture an image and delete an image. After you update the image, you must unmount it and either commit or discard the changes that you have made.

This topic discusses DISM commands related to image management. To see other command-line options, see Deployment Image Servicing and Management (DISM) Command-Line Options. For more information about common DISM scenarios, see DISM Overview (Deployment Image Servicing and Management).

In addition to the command-line tool, DISM is available by using Windows PowerShell. For more information, see Deployment Imaging Servicing Management (DISM) Cmdlets in Windows PowerShell.

The following commands can be used to mount, unmount, capture, append, and delete and query .wim, .vhd and .vhdx files. These options are not case sensitive.

 

Option/Argument Description

Option: /Append-Image

Arguments:

/ImageFile:<path_to_image_file>

/CaptureDir:<source_directory>

/Name:<image_name>

[/Description:<image_description>]

[/ConfigFile:<configurtion_file.ini>]

[/Bootable]

/WIMBoot

[/CheckIntegrity]

[/Verify]

[/NoRpFix]

Adds an additional image to a .wim file. /AppendImage compares new files to the resources in the existing .wim file specified by the /ImageFile argument, and stores only a single copy of each unique file so that each file is only captured once. The .wim file can have only one assigned compression type. Therefore, you can only append files with the same compression type.

This command-line option does not apply to virtual hard disk (VHD) files.

ImportantImportant
Ensure that you have enough disk space for the /Append-Image option to run. If you run out of disk space while the image is being appended, you might corrupt the .wim file.

Use /WIMBoot to append the image with Windows image file boot (WIMBoot) configuration. This only applies to Windows 8.1 Update images that have been captured or exported as a WIMBoot file. For more information about WIMBoot, see Windows Image File Boot (WIMBoot) Overview

/ConfigFile specifies the location of a configuration file that lists exclusions for image capture and compress commands. For more information, see DISM Configuration List and WimScript.ini Files.

/Bootable marks a volume image as being a bootable image. This argument is available only for Windows PE images. Only one volume image can be marked as bootable in a .wim file.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

/Verify checks for errors and file duplication.

/NoRpFix disables the reparse point tag fix. A reparse point is a file that contains a link to another file on the file system. If /NoRpFix is not specified, reparse points that resolve to paths outside of the value specified by /ImageFile will not be captured.

Example:

Dism /Append-Image /ImageFile:install.wim /CaptureDir:D:\ /Name:Drive-D

Option: /Apply-Image

Arguments:

/ImageFile:<path_to_image_file>

[/SWMFile:<pattern>]

/ApplyDir:<target_directory>

{/Index:< image_index> | /Name:<image_name>}

[/CheckIntegrity]

[/Verify]

[/NoRpFix]

[/ConfirmTrustedFile]

[/WIMBoot]

Applies an image to a specified drive.

This command-line option does not apply to virtual hard disk (VHD) files.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

/Verify checks for errors and file duplication.

/NoRpFix disables the reparse point tag fix. A reparse point is a file that contains a link to another file on the file system. If /NoRpFix is not specified, reparse points that resolve to paths outside the value specified by /ImageFile will not be captured.

/SWMFile enables you to reference split .wim files (SWMs). pattern is the naming pattern and location of split files. You can also specify wildcard characters. For example, "E:\image\install*.swm" will apply all of the split files in the E:\image directory named install1.swm, install2.swm, and so on.

/ConfirmTrustedFile validates the image for Trusted Desktop on a Windows 8 or Windows 8.1. This option can only be run on a computer running at least Windows® Preinstallation Environment (Windows PE) 4.0.

noteNote
When using /Apply-Image with the /ConfirmTrustedFile option in Windows PE, always specify the /ScratchDir option pointed to a physical media location. This ensures that short file names will always be available. See DISM Global Options for Command-Line Syntax for more information about the default behavior of the /ScratchDir option.

Use /WIMBoot to apply the image with Windows image file boot (WIMBoot) configuration. This only applies to Windows 8.1 Update images that have been captured or exported as a WIMBoot file. For more information about WIMBoot, see Windows Image File Boot (WIMBoot) Overview

Example:

Dism /apply-image /imagefile:install.wim /index:1 /ApplyDir:D:\

Dism /apply-image /imagefile:install.swm /swmfile:install*.swm /index:1 /applydir:D:\

Option:/Capture-CustomImage

Arguments:

/CaptureDir:<source_directory>

[/ConfigFile:<configuration_file.ini>]

[/CheckIntegrity]

[/Verify]

[/ConfirmTrustedFile]

/Capture-CustomImage captures the incremental file changes based on the specific install.wim file to a new file, custom.wim for a WIMBoot image. You can’t capture an empty directory.

The captured files are converted to pointer files. The custom.wim is placed in the same folder next to the install.wim.

For more information about the full WIMBoot deployment process, see Deploy WIMBoot Images: If you know the size of the images upfront.

ImportantImportant
  • /Capture-CustomImage only captures the customization files. It can’t be used to capture installation files into a new WIM.

  • Keep the install.wim and custom.wim files together. Don't switch out either the custom.wim file or the install.wim file.

  • You can only capture the custom image once. Don’t remove or recapture a custom.wim after capturing the incremental file changes.

/CaptureDir: specifies the directory to which the image was applied and customized.

/ConfigFile specifies the location of a configuration file that lists exclusions for image capture and compress commands. For more information, see DISM Configuration List and WimScript.ini Files.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

/Verify checks for errors and file duplication.

/ConfirmTrustedFile validates the image for Trusted Desktop on a Windows 8 or Windows 8.1. This option can only be run on a computer running at least Windows® Preinstallation Environment (Windows PE) 4.0.

Example:

Dism /Capture-CustomImage /CaptureDir:D:\

Option:/Capture-Image

Arguments:

/ImageFile:<path_to_image_file>

/CaptureDir:<source_directory>

/Name:<image_name>

[/Description:<image_description>]

[/ConfigFile:<configuration_file.ini>]

[/Compress:{max|fast|none}]

[/Bootable]

[/CheckIntegrity]

[/Verify]

[/NoRpFix]

[/WIMBoot]

Captures an image of a drive to a new .wim file. Captured directories include all subfolders and data. You cannot capture an empty directory. A directory must contain at least one file.

This command-line option does not apply to virtual hard disk (VHD) files.

ImportantImportant
DISM will ignore extended attributes during a capture operation.

/ConfigFile specifies the location of a configuration file that lists exclusions for image capture and compress commands. For more information, see DISM Configuration List and WimScript.ini Files.

/Compress specifies the type of compression used for the initial capture operation. The maximum option provides the best compression, but takes more time to capture the image. The fast option provides faster image compression, but the resulting files are larger than those compressed by using the maximum option. This is also the default compression type that is used if you do not specify the argument. The none option does not compress the captured image at all.

/Bootable marks a volume image as being a bootable image. This argument is available only for Windows PE images. Only one volume image can be marked as bootable in a .wim file.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

/Verify checks for errors and file duplication.

/NoRpFix disables the reparse point tag fix. A reparse point is a file that contains a link to another file on the file system. If /NoRpFix is not specified, reparse points that resolve to paths outside the value specified by /ImageFile will not be captured.

Use /WIMBoot to capture the image with Windows image file boot (WIMBoot) configuration. This only applies to Windows 8.1 Update images that you want to capture as a WIMBoot file. For more information about WIMBoot, see Windows Image File Boot (WIMBoot) Overview

Example:

Dism /Capture-Image /ImageFile:install.wim /CaptureDir:D:\ /Name:Drive-D

Option: /Cleanup-Mountpoints

Deletes all of the resources associated with a mounted image that has been corrupted. This command will not unmount images that are already mounted, nor will it delete images that can be recovered using the /Remount-Image command.

Example:

Dism /Cleanup-Mountpoints

Option: /Commit-Image

Arguments:

/MountDir:<path_to_mount_directory>

[/CheckIntegrity]

[/Append]

Applies the changes that you have made to the mounted image. The image remains mounted until the /Unmount-Image option is used.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations./CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

/Append adds the modified image to the existing .wim file instead of overwriting the original image.

The /CheckIntegrity and /Append arguments do not apply to virtual hard disk (VHD) files.

Example:

Dism /Commit-Image /MountDir:C:\test\offline

Option: /Delete-Image

Arguments:

/ImageFile:<path_to_image_file>

{/Index:<image_index> | /Name:<image_name>}

[/CheckIntegrity]

Deletes the specified volume image from a .wim file that has multiple volume images. This option deletes only the metadata entries and XML entries. It does not delete the stream data and does not optimize the .wim file.

This command-line option does not apply to virtual hard disk (VHD) files.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

Example:

Dism /Delete-Image /ImageFile:install.wim /Index:1

Option: /Export-Image

Arguments:

{/SourceImageFile:<path_to_image_file> | /SWMFile:<pattern>}

{/SourceIndex:<image_index> | /SourceName:<image_name>}

/DestinationImageFile:<path_to_image_file>

[/DestinationName:<Name>]

[/Compress:{fast|max|none|recovery}]

[/Bootable]

[/WIMBoot]

[/CheckIntegrity]

Exports a copy of the specified image to another file. The source and destination files must use the same compression type. You can also optimize an image by exporting to a new image file. When you modify an image, DISM stores additional resource files that increase the overall size of the image. Exporting the image will remove unnecessary resource files.

This command-line option does not apply to virtual hard disk (VHD) files.

/SWMFile enables you to reference split .wim files. pattern is the naming pattern and location of split files. You can also specify wildcard characters. For example, "E:\image\install*.swm" will export the split files in the E:\image directory named install1.swm, install2.swm, and so on.

/Compress specifies the type of compression used for the initial capture operation. The /Compress argument does not apply when you export an image to an existing .wim file, you can only use this argument when you export an image to a new .wim file. The maximum option provides the best compression, but takes more time to capture the image. The fast option provides faster image compression, but the resulting files are larger than those compressed by using the maximum option. This is also the default compression type that is used if you do not specify the argument. Use the recovery option to export push-button reset images. The resulting files are much smaller in size, which in turn, greatly reduce the amount of disk space needed for saving the push-button reset image on a recovery drive. The destination file must be specified with an .esd extension. The none option does not compress the captured image at all.

/Bootable marks a volume image as being a bootable image. This argument is available only for Windows PE images. Only one volume image can be marked as bootable in a .wim file.

Use /WIMBoot to apply the image with Windows image file boot (WIMBoot) configuration. This only applies to Windows 8.1 Update images that you want to export as a WIMBoot file. For more information about WIMBoot, see Windows Image File Boot (WIMBoot) Overview

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

Example:

Dism /Export-Image /SourceImageFile:install.wim /SourceIndex:1 /DestinationImageFile:install2.wim

Option: /Get-MountedImageInfo

Lists the images that are currently mounted and information about the mounted image such as whether the image is valid, read/write permissions, mount location, mounted file path, and mounted image index.

Example:

Dism /Get-MountedImageInfo

Option: /Get-ImageInfo

Arguments:

/ImageFile:<path_to_image.wim>

[{/Index:<Image_index> | /Name:<Image_name>}]

Displays information about the images that are contained in the .wim, vhd or .vhdx file. When used with the /Index or /Name argument, information about the specified image is displayed, which includes if an image is a WIMBoot image, if the image is Windows 8.1 Update, see Take Inventory of an Image or Component Using DISM. The /Name argument does not apply to VHD files. You must specify /Index:1 for VHD files.

Example:

Dism /Get-ImageInfo /ImageFile:C:\test\offline\install.wim

Dism /Get-ImageInfo /ImageFile:C:\test\images\myimage.vhd /Index:1

Option: /Get-WIMBootEntry

Arguments:

/Path:<volume_path>

Use /Get-WIMBootEntry to display WIMBoot configuration entries for the specified disk volume.

For more information about how to display WIMBoot configuration entries, see Take Inventory of an Image or Component Using DISM.

This only applies to Windows 8.1 Update.For more information about WIMBoot, see Windows Image File Boot (WIMBoot) Overview

Example:

Dism /Get-WIMBootEntry /Path:C:\

Option: /List-Image

Arguments:

/ImageFile:<path_to_image_file>

{/Index:<image_index> | /Name:<image_name>}

Displays a list of the files and folders in a specified image.

This command-line option does not apply to virtual hard disk (VHD) files.

Example:

Dism /List-Image /ImageFile:install.wim /Index:1

Option: /Mount-Image

Arguments:

/ImageFile:<path_to_image>

{/Index:<image_index> | /Name:<image_name> }

/MountDir:<path_to_mount_directory>

[/ReadOnly]

[/Optimize]

[/CheckIntegrity]

Mounts an image from a .wim, .vhd or .vhdx file to the specified directory so that it is available for servicing.

/ReadOnly sets the mounted image with read-only permissions. Optional.

noteNote
An index or name value is required for most operations that specify a .wim file.

You can use /Optimize to reduce initial mount time.

ImportantImportant
When using the /optimize argument, processes that are ordinarily performed during a mount will instead be completed the first time that you access a directory. As a result, there may be an increase in the time that is required to access a directory for the first time after mounting an image using the /optimize argument.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

Example:

Dism /Mount-Image /ImageFile:C:\test\images\myimage.wim /index:1 /MountDir:C:\test\offline

Dism /Mount-Image /ImageFile:C:\test\images\myimage.vhd /index:1 /MountDir:C:\test\offline /ReadOnly

/Optimize-Image /WIMBoot

Performs specified configurations to an offline image.Use /WIMBoot to configure an offline image for installing on a Windows image file boot (WIMBoot) system.

/Optimize-Image /WIMBoot only applies to Windows 8.1 Update images that have been captured or exported as a WIMBoot file. For more information about WIMBoot, see Windows Image File Boot (WIMBoot) Overview.

ImportantImportant
Only use /Optimize-Image with images that will be used for WIMBoot supported systems. If /Optimize-Image is used with a non-WIMBoot supported system image, Windows may not work as expected, after installation on a non-WIMBoot supported device.

Examples:

DISM.exe /Image:C:\test\offline /Optimize-Image /WIMBoot

Option: /Remount-Image

Arguments:

/MountDir:<path_to_mount_directory>

Remounts a mounted image that has become inaccessible and makes it available for servicing.

Example:

Dism /Remount-Image /MountDir:C:\test\offline

Option: /Split-Image

Arguments:

/ImageFile:<path_to_image_file>

/SWMFile:<path_to_swm>

/FileSize:<MB-Size>

[/CheckIntegrity]

Splits an existing .wim file into multiple read-only split .wim files.

This option creates the .swm files in the specified directory, naming each file the same as the specified path_to_swm, but with an appended number. For example, if you set path_to_swm as c:\Data.swm, this option creates a Data.swm file, a Data2.swm file, a Data3.swm file, and so on, defining each portion of the split .wim file and saving it to the C:\ directory.

This command-line option does not apply to virtual hard disk (VHD) files.

/FileSize specifies the maximum size in megabytes (MB) for each created file.

noteNote
If a single file is larger than the value specified in the /FileSize option, one of the split .swm files that results will be larger than the value specified in the /FileSize option, in order to accommodate the large file.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

Example:

Dism /Split-Image /ImageFile:install.wim /SWMFile:split.swm /FileSize:650

Option: /Unmount-Image

Arguments:

/MountDir:<path_to_mount_directory>

{/Commit | /Discard}

[/CheckIntegrity]

[/Append]

Unmounts the .wim, .vhd or .vhdx file and either commits or discards the changes that were made when the image was mounted.

You must use either the /commit or /discard argument when you use the /Unmount-Image option.

/CheckIntegrity detects and tracks .wim file corruption when used with capture, unmount, export, and commit operations. /CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with apply and mount operations.

/Append adds the modified image to the existing .wim file instead of overwriting the original image.

The /CheckIntegrity and /Append arguments do not apply to virtual hard disk (VHD) files.

Example:

Dism /Unmount-Image /MountDir:C:\test\offline /commit

Dism /Unmount-Image /MountDir:C:\test\offline /discard

Option: /Update-WIMBootEntry

Arguments:

/Path:<Volume_path>

/DataSourceID:<Data_source_id>

/ImageFile:<Renamed_image_path>

Use /Update-WIMBootEntry Updates the WIMBoot configuration entry, associated with the specified data source ID, with the renamed image file or moved image file path.

noteNote
/Update-WIMBootEntry requires a restart in order for any updates to take effect.

Use /Path to specify the disk volume of the WIMBoot configuration.

Use /DataSourceID to specify the data source ID as displayed by /Get-WIMBootEntry.

This only applies to Windows 8.1 Update.For more information about WIMBoot, see Windows Image File Boot (WIMBoot) Overview

Example:

DISM.exe /Update-WIMBootEntry /Path:C:\ /DataSourceID:0 /ImageFile:R:\Install.wim
