Open USER File

If you've ever come across a file with the extension ".USER," you might wonder what kind of file it is and how to open or use it. The truth is that there isn't a single answer to this question, as USER files can have multiple applications, depending on the software that created them. In this article, we will explore the various formats and ways to open and use files with a USER file extension, as well as provide some important information about these files.

Visual Studio Project User Options

One common use of the USER file extension is in Microsoft Visual Studio. In this context, a USER file contains user-specific project settings and options. These files are created and used exclusively by Visual Studio and are not meant to be directly edited or manipulated. To open a USER file with Visual Studio, simply locate the file in your project folder and double-click on it. Visual Studio should open the file automatically and display the contained settings. More information on Visual Studio Project User Options can be found on the Microsoft Visual Studio documentation website.


Another application that uses the USER file extension is AutoCAD, a popular computer-aided design (CAD) program. In AutoCAD, a USER file stores user interface settings, making it possible for users to customize their work environment. To open and edit a USER file in AutoCAD directly, click on the gear-like icon in the lower-right corner of the screen, then select "Options" in the dialogue window that appears. Next, click on the "Profiles" tab and choose "Export" to save a copy of your current settings to a USER file. Import settings from another USER file by clicking "Import" and selecting the desired file. Visit the AutoCAD support website's AutoCAD Options Dialog for more detailed instructions.


SolidWorks, a 3D CAD software, also uses the USER file extension to store user-specific settings such as keyboard shortcuts, menus, and toolbars. These files are part of the SolidWorks registry and can be exported and imported through the SolidWorks User Interface. To do this, go to "Tools" > "Save/Restore Settings" and follow the prompts to either save your settings to a USER file or restore settings from an existing USER file. SolidWorks has multiple resources available on its MySolidWorks website to help with USER files and other aspects of the software.
