.MCH File Extension

The mch file extension was in the past used for so called Macromedia Xtra extensions, "plug-in" code modules that let users add specialized capabilities and extended functionality to Macromedia products.

When placed in an application's Xtra extensions folder, Xtra extensions integrate their commands, palettes, and functionality into the application. In addition, Xtra extensions provided by Macromedia allow you to use other third party "plug-in" types and filters in Macromedia applications.

Xtra extensions are based on the Macromedia Open Architecture (MOA), which provides a common extension mechanism for Macromedia and third-party developers to enhance the capabilities of Macromedia products. Because Macromedia is incorporating MOA into all of its applications, developers will find it easy to develop Xtra extensions that work not only cross-platform (Windows, MacOS, etc.) but across multiple Macromedia products. For example, Transition Xtra extensions work in both Director and Authorware, and the same MIX image import Xtra extensions work across the products in the FreeHand Graphics Studio.

Macromedia is now owned by Adobe.

.MCH file format is deprecated and this file format is no longer supported.

Currently, .MCH file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.

How to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .mch file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
