Open MOF File
The MOF filename extension stands for Managed Object Format (MOF) and its associated file type.
The MOF file format is based on the Interface Definition Language (IDL), MOF is a text-based format and a formal language within the Microsoft Windows Management Instrumentation (WMI) framework.
A MOF file is a text file that contains a series of statements in MOF syntax.
Formally, the purpose of the MOF file is to manage classes, providers, properties, and more, for a given WMI repository, by defining attributes for resources managed by WMI.
MOF files were primarily used with (legacy) Microsoft Systems Management Server (SMS) software, with "SMS_DEF.mof" being the default MOF file.
MOF files are modified by system administrators as needed, using a text editor.
A modified MOF file must be compiled for the changes to take effect.
MOF files are programmed in a language derived from Microsoft Visual C++ syntax.
They can be compiled into the WMI repository using the Mofcomp.exe program.
They are usually accompanied by a corresponding DLL dynamic library file, which contains the skeleton code that returns the data defined in the MOF file.
The MOF file format and compiler were developed by the Desktop Management Task Force (DMTF).
