What is a .APPCONTENT-MS file?
An .APPCONTENT-MS file is a type of Application Content File used by certain Windows applications to enhance their in-app search functions. This file format stores details about the app's content in XML format, which includes important keywords and properties. These details are used by the application when it accesses the Windows.Storage.Search API to help perform searches within the app more effectively.
The content stored in an .APPCONTENT-MS file can vary depending on the application it is associated with. For example, in social media apps like Facebook or communication apps like Skype, the file might contain user information such as full names, birthdates, phone numbers, home addresses, or the last login details.
Typically, these files are located in a deep system folder, specifically in the %Appdata%\Local directory, and are not meant to be directly interacted with by users. They are automatically managed and referenced by the applications that use them.
However, if you are curious or need to view the contents of an .APPCONTENT-MS file for any reason, you can open it using any standard text editor or an XML editor. Since the file is in XML format, opening it with an XML editor might provide a clearer view of the structured data it contains.
Common text editors that can be used to open these files include Notepad on Windows, TextEdit on macOS in plain text mode, or any other text editing software that supports plain text or XML files. It's important to note that manually editing these files is not recommended as it could disrupt the functioning of the associated application.
