HWOF files belong to Microsoft's Office productivity software for Apple macOS and Mac OS X systems. They provide help-related content for Microsoft Office for Mac.
The file is a supporting resource for the Office help system and is not one of the application's normal user document formats. Its contents are intended to be accessed through the compatible Office for Mac installation.
Open the HWOF file with the compatible version of Microsoft Office for Mac on macOS or Mac OS X. It may be loaded automatically by the Office help system rather than opened as a standalone file.
If the file does not open through Office, the version of Office or the operating system may no longer support this help resource.
An HWOF file is a help-system resource, not a user document, so it has no useful standard conversion to formats such as PDF or word-processing documents.
When the file can be accessed through a compatible Office for Mac installation, required information can be copied from the displayed help content manually.
