.MDC Estensione file

Audio file created by MidiCo, a Mac program used for making karaoke music; supports imported audio from MIDI (.MID) and .MP3 formats; also supports multiple text tracks that allow independent synchronization on the music timeline; used for saving and loading karaoke projects.

MDC files can be exported to MP3 files when complete.

An MDC file is a text-based file used by Anysphere Cursor to define project rules and instructions. It stores content in Markdown format and typically includes structured metadata that helps define how the editor or its AI features should behave within a project. MDC files are plain text and typically include both human-readable instructions and machine-readable structure.

In Cursor, MDC files are used as part of its rules system to guide AI behavior and coding assistance. They are commonly stored in a project's .cursor/​rules/​ directory and help define how the AI should respond, follow conventions, or apply project-specific guidelines.

The format may include Markdown content along with structured metadata that the editor interprets when applying rules during development work. These files are mainly used in software development environments where teams want consistent AI-assisted coding behavior.

Developers and technical teams working on projects that use Cursor for AI-assisted programming are most likely to encounter MDC files. They help enforce consistent project standards and provide contextual instructions that the editor can apply automatically while generating or modifying code.

You can open MDC files with any text editor since they are stored as plain UTF-8 text files with Markdown formatting. Examples of text editors that can open MDC files include Microsoft Notepad and Apple TextEdit.

In Cursor, you can open it by using File → Open, dragging the file into the editor, or selecting it from the project file explorer if it is already included in your workspace. When opened this way, the file appears as editable Markdown text, which allows you to view or modify its contents. However, Cursor only applies the file to its AI rules system when the MDC file is placed in the project's .cursor/​rules/​ directory, not when it is opened manually.

An MDC file is a camera raw image created by a Minolta digital camera such as the Minolta RD-175. It stores image data that the camera captured and then saved on the camera's storage device. Photographers often transfer MDC files to their computers for photo editing and then save the result to a format such as JPEG which can be shared.

MDC is not a common camera raw format. You will most likely only encounter an MDC file if you take photographs with the Minolta RD-175 camera or if you receive an MDC camera raw image from a friend or co-worker sharing an image captured with a Minolta camera.

There are several software programs, as well as software development kits, that support the MDC format. One software development kit that supports MDC is LibRaw.

Street map project file created by Merkaartor, a free, cross-platform OpenStreetMap (OSM) editor; saved using XML formatting and contains a street map made up of roads, areas, points of interest (POIs), and annotations; used for saving street map projects.

An MDC file is a 3D model saved in a format used by the video games Return to Castle Wolfenstein and Wolfenstein: Enemy Territory. It contains a mesh, colorization data, shading data, and animation data. The animation data an MDC file contains is compressed.

Return to Castle Wolfenstein and Wolfenstein: Enemy Territory are entries in the Wolfenstein series of first-person shooter video games. Return to Castle Wolfenstein was developed primarily by Gray Matter Studios and released in 2001. Wolfenstein: Enemy Territory was developed by Splash Damage and released in 2003.

Both games use 3D models saved in the MDC format. The MDC format is similar to the .MD3 format, except the animation data MDC files contain is compressed. This can result in similar models having much smaller file sizes when saved in the MDC format.

MDC files are not meant to be opened outside the games in which they are used. However, Wolfenstein modders have created the RtCW:ET Blender Model Tools add-on to allow them to open MDC files (and other types of Wolfenstein 3D models) in Blender.
