A vjsproj file belongs to Microsoft Visual J#, Microsoft's development environment for creating programs with the Visual J# language.
The file contains the project definition, including references to source files and other project items, together with information used to manage and build the project. It works as part of a Visual J# project rather than as a standalone source-code file.
Visual J# was designed for Microsoft Windows and is now obsolete. The format is therefore mainly encountered in older Visual J# projects.
Open the vjsproj file in Microsoft Visual J# on Microsoft Windows. Use the development environment's project-opening command rather than treating the file as a standalone program.
Current software may not support this obsolete project format. A text editor can display the file's contents, but it will not provide the Visual J# project features.
To preserve a vjsproj file, open it with Microsoft Visual J# and recreate or migrate the project in a current development environment.
Project source files and other resources may need to be migrated separately; changing the project file extension alone does not convert the project.
