What is a USER file?

USER files mostly belong to Microsoft Visual Studio. USER files store user-specific configuration settings for applications. They often contain data specific to a project, such as window layouts, build preferences, and other personal options.
In Microsoft Visual Studio, for instance, these files hold project user settings in a structured format (using UTF-8 encoded XML) to remember how you customized your working environment.
Other applications like Hero Lab and Qt Creator use similar files to save user preferences for smoother operation and a personalized experience.
  • User Settings: These files record settings unique to an individual user.
  • Project Specific: They store information particular to a project, keeping changes separate from the main project files.
  • Structured Format: The content is usually XML-based (using UTF-8 or plain XML).
  • Automatic Handling: The application generates and updates them automatically when you change settings.
  • FilExt.com tips: When you open a project, the software reads the USER file to restore your environment. It is best to modify these settings through the program interface rather than editing the file directly. For more detailed information about Visual Studio's handling of these files, visit the Visual Studio website.

    How to open a USER file

    You need a suitable software like Microsoft Visual Studio to open a USER 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 USER file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a USER file directly in the browser:. Just drag the file onto this browser window and drop it.
