What is the .GADGET file type?
The .gadget extension is related to the Sidebar Gadget concept in Microsoft (MS) Windows 7/8 and denotes sidebar gadget files. A Windows gadget is a small application with a fixed viewport attached to a sidebar on the Windows desktop, usually a handy tool like a calendar, weather informer, alarm clock etc. Windows Vista/7/8 includes a set of standard gadgets.
A .gadget file is a ZIP archive containing resource files required by the gadget program. Any gadget must include a gadget manifest file with the exact name 'gadget.xml' that contains definition of the gadget as an entity. Gadget definition is XML-based. An .html file linked to the manifest provides all functionality through the use of HTML, CSS, JavaScript etc.
In Windows Vista/7/8, the .gadget extension is pre-associated to the sidebar handler by default, and so any downloaded GADGET files are properly opened with a double-click. Windows XP does not natively have sidebar functionality, however, there are sidebar utilities for this operating system that can use and install .gadget packages.
