UncompressEx method of the Win32_PageFile class

The UncompressEx WMI class method uncompresses the logical paging file (or directory) specified in the object path. This method is an extended version of the Uncompress method.

This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.

Syntax

uint32 UncompressEx(
  [out]          string  StopFileName,
  [in, optional] string  StartFileName,
  [in, optional] boolean Recursive
);

Parameters

StopFileName [out]

Name of the file or directory where the UncompressEx method failed. This parameter will be null if the method succeeds.

StartFileName [in, optional]

Names the child file or directory to use as a starting point for UncompressEx. The StartFileName parameter is typically the StopFileName parameter specifying the file or directory at which an error occurred from the previous method call. If this parameter is NULL, the operation is performed on the file or directory specified in the ExecMethod call.

Recursive [in, optional]

If true, the change of ownership will be applied recursively to the files and directories within the directory specified by the CIM_LogicalFile instance.

Note

For file instances, the Recursive parameter is ignored.
