HTC Home is a Microsoft Windows utility that provides widgets similar to those used with the HTC Sense launcher on smartphones. The .hhpack format is used for distributing additional HTC Home widgets.
An .hhpack file is a package of widget installation data that HTC Home uses when adding an extension. It is not intended to be opened as a document or used independently of HTC Home.
Use HTC Home on Microsoft Windows to install an .hhpack file. The package should be opened through HTC Home or its widget installation feature rather than a general-purpose application.
It may not be possible or useful to convert .hhpack files to another format. Install the file with HTC Home if you need to use the widget it contains.
Software applications that can open hhpack files:
