File type: Project File
You're here because you have a file that has a file extension ending in .prj. Files with the file extension .prj can only be launched by certain applications. It's possible that .prj files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .prj file?

The PRJ file extension is used to indicate data files which are used by multiple programs to save project data and settings. Such files may also include reference to other files or projects. Some of the programs that make use of PRJ files are Microsoft’s Visual Studio, Autodesk’s AutoCAD, Steinberg’s WaveLab, and many more. PRJ files are basically generic project files and can be opened through the application that created it. To view installed programs capable of opening PRJ files, users may open the Windows File context menu. PRJ files are not advised to be opened manually through softwares except ithe authoring one, as doing so may cause irreversible damage to the file.

how to open a .prj file?

Launch a .prj file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .prj file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .prj files aren't yet associated with it. In this case, when you try to open a .prj file, you can tell Windows which application is the correct one for that file. From then on, opening a  .prj file will open the correct application.

Microsoft Visual Studio

Microsoft Visual Studio

Microsoft Visual Studio is an integrated development environment (IDE) produced by Microsoft. It has a code editor that supports syntax highlighting and code completion using IntelliSense for not only variables, functions and methods but also language constructs like loops and queries; includes a debugger that works both as a source-level debugger and as a machine-level debugger; includes a host of visual designers to aid in the development of applications and other tools. Visual Studio permits developers to write extensions for Visual Studio to expand its capabilities. These extensions are linked to Visual Studio and extend its functionality. Extensions come in the form of macros, add-ins, and packages. Macros represent repeatable tasks and actions that developers can write programmatically for saving, replaying, and distributing; add-ins gives access to the Visual Studio object model and can interact with the IDE tools; and packages can create designers and other tools, as well as integrate other programming languages.

a word of warning

Be careful not to rename the extension on .prj files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .prj. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
