XAP is the file format for:
- mobile apps for the Windows Phone operating system
- Silverlight web apps
Since the relase of Windows Phone 8.1 XAP was replaced by the the APPX file format used to install WinRT apps on the Windows Phone Support.
- Speedy Blupi for Windows Phone uses the XAP file format, this means we can ignore APPX.
A XAP file is a ZIP file, but which has the xap file extension (not zip).
The MIME type for XAP files is: appilcation/x-silverlight-app.
Microsoft later enabled the possibility to encrypt the XAP file. A standard ZIP extractor does not work for encrypted XAP files.
- Fortunately, the XAP file of Speedy Blupi is not encrypted and can be opened as a standard ZIP file.
Content of a XAP file
- AppManifest.xaml file
- DLLs, which are required
- Application / Game resources (images and others)
