A file with .mf extension is a Java Manifest file. It contains information about JAR file entries. The MF file itself is contained inside the JAR file. It provides extension and package-related definitions. JAR files can be executable files. In such cases, the manifest file specifies the main class with a public static void main statement. Manifest files are named MANIFEST.MF. They can be opened with any text editor.

Manifest file format specifications are by Oracle. They are in their JAR file format guide. Java Manifest Format specification was created by Sun Microsystems. MF file format is compatible with Linux, Mac OS, Windows platforms.

If an application is bundled in a JAR file, the Java Virtual Machine needs the entry point. An entry point is any class with a public static void main method. This is provided in the Main-Class header.

The manifest file is named MANIFEST.MF. It is under the META-INF directory in the JAR. It’s a list of key and value pairs, called headers or attributes. These supply metadata to describe the JAR.

A manifest file is added automatically when creating a JAR. We can also specify our own. The default has basic headers like Manifest-Version and Created-By.

The MF file extension is related to METAFONT. METAFONT is the brother of TEX, the typesetting program. The mf file stores font for LaTeX. To open: Use compatible tools to work with mf files. To convert: This .mf file type can’t be converted to any other format. This is the case for some proprietary or closed file formats.

Description: The MF file is a Metafont Font. Metafont defines vector fonts. MF format description. Equally important is to generate a TFM file. A TFM file is generated when the fontmaking variable is positive. Traditionally TEX distributions have come with TFM files pregenerated. Someone installing a Metafont font must generate its TFM file before TeX can use it. A third Metafont operation is proof mode. The bitmap font file contains additional information via commands when the proofing variable is positive.

The .MF file contains metadata about Java archives. It includes what files the archive contains and their purpose. Manifest files have the pathname META-INF/MANIFEST.MF. They are saved with the JAR file. The default manifest file can be modified with a text editor.
