What is an APPX file?

App package format introduced with Windows 8; used by developers when packaging and submitting Windows 8 apps (formerly referred to as Metro Style apps) for sale on the Windows Store.

More Information

APPX files can be packaged with Visual Studio 2012, which provides support for developing Windows 8 apps. Use the Create App Packages wizard by choosing Project → Store → Create App Packages in Visual Studio or Store → Create App Packages in Visual Studio Express.

APPX files can be included within .APPXUPLOAD files. Both file types can be used as a submission format to the Windows Store, but APPXUPLOAD files contain additional information that allows debugging information to be sent back to the developer for app crashes.

NOTE: APPX files have a 2GB maximum file size.
