Split-WindowsImage

Windows Server 2012 R2 and Windows 8.1

Updated: April 2, 2014

Applies To: Windows 8.1, Windows PowerShell 4.0, Windows Server 2012 R2

Split-WindowsImage

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

Syntax

Parameter Set: Default
Split-WindowsImage -FileSize <UInt64> -ImagePath <String> -SplitImagePath <String> [-CheckIntegrity] [-LogLevel <LogLevel> {Errors | Warnings | WarningsInfo} ] [-LogPath <String> ] [-ScratchDirectory <String> ] [ <CommonParameters>]




Detailed Description

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.

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

This cmdlet does not apply to virtual hard disk (VHD) files.

Parameters

-CheckIntegrity

Detects and tracks .wim file corruption when used with the Add—WindowsImage, Dismount-WindowsImage or Save-WindowsImage cmdlet. CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with the Expand-WindowsImage or Mount-WindowsImage cmdlet.

-LogPath<String>

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.

-ScratchDirectory<String>

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.
