.VDPROJ File Extension

Software development project created by Visual Studio, an application that allows developers to create Windows programs; stores project build settings and file references; often used for building and packaging Windows installation programs.

Setup and deployment projects are commonly built into .MSI or .EXE files, which can are used for software installation in Windows. VDPROJ files are saved in a text format and can be viewed with a text editor if needed.

NOTE: Previously, setup and deployment projects were saved with the .VDP extension.
