What is an MLP file?

MLP files mostly belong to MeshLab. Some MLP files are used in a very specialized way.
  • 3D Image Files: Certain MLP files hold 3D image data. They are linked with companies like Malpha and can be used to store raster images for older systems such as the Apple II.
  • Lossless Audio Compression: Other MLP files use the Meridian Lossless Packing format. They serve to compress audio without loss and work with tools like Dolby Atmos Renderer and MLPlayer.
  • MeshLab Projects: A group of these files is used as project files within MeshLab, a tool for 3D mesh processing. More information is available at MeshLab.
  • Construction Cost Data: There are also MLP files that store construction cost estimates in a JetDB format, supported by MII Standard Jet DB.
  • FilExt.com tip: In all cases the file extension does not tell its function alone. To choose the right viewing or editing software, check the file header or use a hex editor to match the internal format.

    How to open an MLP file

    You need a suitable software like MeshLab to open an MLP file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MLP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MLP file directly in the browser:. Just drag the file onto this browser window and drop it.

    MLP file format:

    Every file has a defined file format, i.e. how the data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the MLP files is as follows:

    The MLP file extension is rather rarely used and is used by a few programs, each with its own file format. The following file formats are most commonly found in MLP files:

    The remaining 50% of all MLP files are different files with different signatures, often, for example, MeshLab Project and JetDB. Often described as mesh, mellinamae, pewniaki, meshlab or scene. If you want to find out which format your MLP file belongs to, just click on the button "Choose your .mlp file to play".
