What is an APPLICATION file?

APPLICATION files mostly belong to .NET by Microsoft. APPLICATION is the file extension for a ClickOnce deployment manifest file. They enable easy, "one click" deployments of user-level Windows applications. ClickOnce is an application deployment technology that is a part of the .NET framework from Microsoft. It allows users to create self-updating Windows applications that can run with minimal user interaction after installation. A ClickOnce application reads the deployment manifest file periodically to check if updates are available. The APPLICATION file stores program deployment properties in an XML format. It contains the name, identity of the publisher, application version, dependencies, and update behavior. It may also contain a digital signature to verify that the assemblies and files are not tampered. Every APPLICATION file has a corresponding APPREF-MS file, which is a Microsoft Application Reference file. APPREF-MS is the file that actually calls on ClickOnce. ClickOnce then executes within the .NET framework in Windows to run the application, as well as check for updates.

How to open APPLICATION files

You need a suitable software like .NET from Microsoft to open an APPLICATION file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your APPLICATION file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a APPLICATION file directly in the browser:. Just drag the file onto this browser window and drop it.

If you can determine the file format, the associated program can also be determined. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). File extension, signature and file format must match; otherwise errors will occur when the file is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. In the following you will find our evaluation of the APPLICATION files:

Files with the APPLICATION extension are quite widely used. This file type is primarily used by a single program. However, the following two file formats are common:

All other APPLICATION files (8%) have different formats, often, for example, XML. These files sometimes refer to giftrap, workflow, online, host, geoserver, dynamics or digital. Drag & drop your file here to see the file format and a preview of your APPLICATION file!

How to solve problems with APPLICATION files

  • Associate the APPLICATION file extension with the correct application.
  • Update your software that should actually open deployment manifest files. Because only the current version supports the latest APPLICATION file format. Search, therefore, e.g. on the Microsoft manufacturer website after an available .NET update.
  • To make sure that your APPLICATION file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
