What is an .MF file?

.MF is Java Manifest File

Contains information about file packages in a Java archive (.JAR file); includes metadata about the archive such as what files it contains and what they are used for; included within the JAR file itself.

Manifest files have the default pathname "META-INF/MANIFEST.MF" and are saved along with the JAR file. The default manifest file can be modified with a basic text editor.

File Type 3 Panda Multifile
Developer by: Panda3D Category: Game Files

An MF file is an archive used by games developed by Panda3D, a free 3D game engine. It contains game resource files, such as sound effects, texture, and models. MF files are compressed with Zip compression.

MF files are created by the "multify" console program included with Panda3D, which can be used to store and extract files from an MF archive. The console program can also be used to encrypt the game resource files stored in the MF archive with a password.

Games that use the MF archive include: Disney's "Pirates of the Caribbean Online" and Autumn Moon Entertainment/Crimson Cow's "A Vampyre Story." Panda3D is developed by Carnegie Mellon University.
