What is a XAP file?
The .XAP file extension usually represents a Silverlight Application Package created by Microsoft Silverlight. It is also commonly used as a Windows Phone application package for legacy mobile devices running Microsoft Windows Phone. Alternatively, the extension can represent an audio workspace file for an XACT Project developed by Microsoft.
How to open XAP files?
Developers typically use the Windows Phone App Deployment Tool or Microsoft Visual Studio to interact with these application packages. viewer.online/xap analyzes .XAP files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
If you need to inspect the contents of a .XAP package manually, you can change the file extension to .ZIP and extract it using standard tools like 7-Zip. This allows you to view internal assets like images and libraries. However, because the .XAP extension has multiple possible meanings, you should not guess the format. We recommend using viewer.online/xap to identify the actual format of your file.
Summary
Because .XAP files use the known ZIP format, viewer.online/xap can safely open and display them online, eliminating compatibility problems.
