mw.fileTypes.labels Extension Point (Beta)

Add custom labels for file type

Since R2024b

Note

Extension points are available only as part of the new desktop for MATLAB^®. The new desktop for MATLAB is in beta development and should not be used for development or production activities. For more information, see Get Started with the New Desktop for MATLAB (Beta).

You can add custom labels for different file types in MATLAB using the mw.fileTypes.labels extension point.

To add a custom label for a file type in MATLAB:

1. Create a JSON-formatted file named extensions.json and place it in a folder named resources.

2. Add a set of JSON declarations to extensions.json that defines one or more labels.

3. Add the folder containing the resources folder to the MATLAB path. To add the folder to the path, use the addpath function or right-click the folder in the Files panel and select Add to Path > Selected Folders and Subfolders.

This JSON code shows the basic structure of the mw.fileTypes.labels extension point.

{
    "mw.fileTypes.labels": {
        "xlsx": "Microsoft Excel Worksheet", 
        "docx": "Microsoft Word Document"
    }
}
