The SMS_G_System_UnknownFile Windows Management Instrumentation (WMI) class is an SMS Provider server class, in System Center 2012 Configuration Manager, that represents an unknown software file, that is, a file that does not contain product resource information or is not related to a software product that contains product resource information.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties.

Class SMS_G_System_UnknownFile : SMS_G_System
{
	 DateTime CreationDate;
	 UInt32 FileCount;
	 SInt64 FileID;
	 String FileDescription;
	 DateTime FileModifiedDate;
	 String FileName;
	 String FilePath;
	 SInt64 FileSize;
	 String FileVersion;
	 DateTime ModifiedDate;
	 UInt32 ProductId;
	 UInt32 ResourceID; 
};

Methods

The SMS_G_System_UnknownFile class does not define any methods.

ResourceID

Data type: UInt32Access type: Read/Write Qualifiers: [key]See SMS_G_System Server WMI Class.

Remarks

There are no special class qualifiers for this class. For more information about both the class qualifiers and the property qualifiers included in the Properties section, see Configuration Manager Class and Property Qualifiers.

Although this class contains the same unknown file information that is found in SMS_G_System_SoftwareFile Server WMI Class, there is no advantage to querying against this class for unknown product files. It is recommended to use SMS_G_System_SoftwareFile for all queries involving inventoried files.

The Software Inventory Agent collects files identified in the site control file. To identify the files to collect, the agent:

  1. Queries the site control SMS_SCI_ClientComp Server WMI Class objects for items having the value "Software Inventory Agent" for the ClientComponentName property.

  2. Loops through the embedded property list. When the value for PropertyName is "Inventoriable Types", the agent updates the comma-delimited list of file names (including extensions) in the Value2 property. When the value for PropertyName is "Inventory Schedule", the agent updates the interval string in the Value2 property. For information about creating an interval string, see the example for the WriteToString Method in Class SMS_ScheduleMethods method. When the value for PropertyName is "Report Options", the agent updates the reporting options value in the Value property, specifying at least one reporting option for the software inventory to be collected. The following table lists the reporting options.

    Reporting option Description

    Product version information. Bit 0.

    Inventories products that contain company and product resource information.

    Files associated with known products. Bit 1.

    Inventories files associated with products that contain company and product resource information. For example, Wwintl32.dll is inventoried because it is associated with Microsoft Word.

    Set this bit only if the product version information reporting option is selected.

    Files not associated with known products. Bit 2.

    Inventories files that do not include company and product resource information (unknown files).
  3. For newly added inventory types, adds entries to the following Path, Subdirectories, and Exclude embedded property lists.

  4. Updates the site control file. For information about updating the site control file, see Configuration Manager Site Control File.

Note
Collecting inventory information for some files, for example, DLL files, can generate a large volume of network traffic and substantially increase the size of the System Center 2012 Configuration Manager database. For this reason, test any changes you make in a test environment before implementing them in a production environment.
