LIBRARY-MS File Extension

Windows Library Description File – file format by Microsoft

LIBRARY-MS is a Windows Library Description File developed by Microsoft. It contains information about a dynamic-link library (DLL) or ActiveX control, including its functions, classes, and data structures.

Technical Definition of a LIBRARY-MS File

A LIBRARY-MS file serves as a Windows Library Description File, containing detailed information about a dynamic link library (DLL). It provides a structured description of the exported functions and their associated data types. LIBRARY-MS files allow applications to dynamically load and link to DLLs at runtime, enabling code sharing and extensibility. These files are typically created using the Microsoft Visual Studio development environment.

Usage and Significance

LIBRARY-MS files play a crucial role in software development on the Windows platform. They enable seamless integration of DLLs into applications, allowing developers to reuse code and create modular software components. By specifying the exported functions and data types, LIBRARY-MS files facilitate efficient and standardized communication between different parts of the software. This file format ensures that the application can correctly locate and utilize the DLL’s functionality when needed, enhancing application performance and reducing development time.

What is a LIBRARY-MS File?

A LIBRARY-MS file is a text file that contains information about a Windows library. This information can include the library’s name, description, version, and the list of files that are included in the library. LIBRARY-MS files are used by the Windows Library Manager (Libman.exe) to manage Windows libraries.

How to Open a LIBRARY-MS File?

LIBRARY-MS files can be opened with a text editor, such as Notepad or WordPad. However, it is not recommended that you edit LIBRARY-MS files directly, as this could damage the file and prevent it from being used by Libman.exe. If you need to edit a LIBRARY-MS file, it is best to use Libman.exe to do so.

If you want to view the contents of a LIBRARY-MS file, you can use Libman.exe to do so. To do this, open a command prompt and type the following command:


libman /list <path_to_library_ms_file>

This command will display the contents of the LIBRARY-MS file in the command prompt window.

LIBRARY-MS File Format

A LIBRARY-MS file is a text file that describes the contents of a Windows Dynamic Link Library (DLL). It contains information such as the names of the DLL’s functions, the data structures it uses, and the resources it contains. LIBRARY-MS files are used by development tools such as Visual Studio to help developers create and debug DLLs.

The LIBRARY-MS file format is a simple text format that is easy to read and edit. It consists of a series of sections, each of which contains information about a different aspect of the DLL. For example, the “EXPORTS” section lists the names of the DLL’s exported functions, while the “IMPORTS” section lists the names of the DLL’s imported functions.

LIBRARY-MS files are an important part of the Windows development process. They help developers create and debug DLLs, and they provide information about the DLL’s contents to other development tools.
