Files with the vjsprojdata file extension belong to Visual J#, a Microsoft programming language and development environment similar to Java and designed for the .NET platform.
A vjsprojdata file stores project-related data used by Microsoft Visual J# and forms part of a Visual J# project rather than being a general-purpose data format.
Visual J# runs on Microsoft Windows. The software and this file format are obsolete and are no longer in active use.
Open the vjsprojdata file with Microsoft Visual J# on Microsoft Windows. It is intended to be opened as part of the Visual J# project that uses it, rather than edited as a standalone document.
Because Visual J# is obsolete, it may be difficult to obtain a compatible installation. Do not expect modern development software to open this file directly.
The vjsprojdata file contains Visual J# project data, so it is not normally converted to a common document or data format.
For migration, open the original project in Visual J# if possible and recreate or port the project manually in a current development environment.
