UncompressEx method of the CIM_DataFile class

The UncompressEx method uncompresses the logical data file (or directory) that is specified in the object path. This method is an extended version of the Uncompress method and is inherited from CIM_LogicalFile.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

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]   string StartFileName,
  [in]   boolean Recursive
);

Parameters

StopFileName [out]

Name of the file (or directory) where the method failed. This parameter is null if the method succeeds.

StartFileName [in]

Child file (or directory) to use as a starting point for this method. Typically, the StartFileName parameter is 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.

If StartFileName is used, Recursive must be set to true as well.

Recursive [in]

If TRUE, the method is also applied recursively to files and directories within the directory that is specified by the CIM_DataFile instance. For file instances, this parameter is ignored.
