Opening APPLICATION files

Did your computer fail to open an APPLICATION file? We explain what APPLICATION files are and recommend software that we know can open or convert your APPLICATION files.

What is an APPLICATION file?

Files that contain the .application file extension are most commonly associated with the ClickOnce technology that was created by Microsoft. These files are saved in the XML format.

ClickOnce is used to deploy Windows Presentation Foundation-based software or Windows Forms. The files contain application deployment information and are created to allow for "one-click" start-up of various Windows applications. The APPLICATION files may also identify the attributes that are used for the updates of the associated application.

An APPLICATION file is similar to a Java Web Start file, however, APPLICATION files are for the Windows operating platform instead of the Java computer platform.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
