Opening PRJ files
Did your computer fail to open a PRJ file? We explain what PRJ files are and recommend software that we know can open or convert your 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.
Software that will open, convert or fix PRJ files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
