.H1V File Extension

Task Metadata (h1v) files are used to define metadata for the tasks (Microsoft AML topics) and resources in each compiled Help file.

The Assistance Platform client (HelpPane.exe) is a new Help engine designed for Windows Vista. It is not compatible with any previous versions of Windows. The Assistance Platform client is required to display Help files with the h1s file name extension.

In Windows Vista, the Assistance Platform client can be customized by OEMs, system builders, and enterprise customers under license agreement, but cannot be used by third-party programs. For more information on customizing the Assistance Platform client, see the Windows SDK.

Unless there are suggested applications listed below the extension description, that are able to convert the system files, there is usually no way to convert system files into any other file format. Any attempts to rename system files is strongly discouraged, as it can cause the system to be corrupted and not work properly.
