The Microsoft Help container format is associated with Microsoft help systems on Windows. An .mshc file is a ZIP-based archive that packages the files belonging to a help collection, including HTML documents, images, and related resources.
Microsoft Windows Help uses these containers to deliver application documentation. The MSHC Migration Utility can be used with MSHC help containers, while FAR HTML provides tools for working with their help content.
On Windows, open the file with Microsoft Windows Help or FAR HTML. The MSHC Migration Utility can also be used when the container needs to be migrated.
FAR HTML can process MSHC files and transform their help content into other formats that it supports.
