Opening PRJ files
What is a PRJ file?
Files that contain the .prj file extension are most commonly used to store project files. The .prj file extension is a generic extension that is used by a variety of different project applications.
PRJ files normally contain the project settings of a project and other project data, including references to other files that may be used by the related project.
Some of the applications that use the .prj file extension for project files include Maestro, Microsoft Visual Basic, Visual Cafe, Turbo C, FireFly SDK and AwpHelp.
Although many software applications use the .prj file extension, not all PRJ files are interchangeable across all applications. This means that a PRJ file that has been created in one application may not be able to be opened with another application that uses the .prj file extension due to differences in the format of the file type.
