What is an MSAPP file?
An MSAPP file is an application created using Microsoft Power Apps Studio, a web-based mobile and web app development platform. It is a Zip-compressed archive that contains all the code and assets required to build an application. Power Apps Studio users can download their applications as MSAPP files by selecting File → Save as → This computer.
Microsoft Power Apps is a web-based development platform that allows developers to create many different types of mobile and web applications. In Power Apps, developers can create:
- Canvas applications
- Model-driven applications
- Portal applications
When a developer creates a canvas application, the app opens in Power Apps Studio, an environment tailored specifically for developing canvas apps. Typically, Power Apps Studio saves developers' apps to the Power Apps cloud. However, developers can also download their apps to their computers, to retain local copies. When they do, the apps are saved as MSAPP files.
Each MSAPP file is a Zip archive, which can be decompressed just like any other Zip archive. When you decompress an MSAPP file, you can view the .JSON, .JPG, .PNG, and other files that make up the app.
How to open an MSAPP file
You can open an MSAPP file in Microsoft Power Apps Studio (Web). To do so, open Power Apps Studio and select Open → Browse. Then, navigate to and open your MSAPP file.
As stated above, you can also decompress an MSAPP file using any Zip-decompression tool, such as 7-Zip (Windows), Apple Archive Utility (Mac), or B1 Free Archiver (cross-platform). Doing so will allow you to view the constituent files your MSAPP file contains. (To decompress your file, you may have to change the .msapp extension to .zip.)
