Notes about the XPJ file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The XPJ file type is primarily associated with 'Micro Planner X-Pert' by Micro Planning International Inc.. Project management and decision making software. MPI released Micro Planner X-Pert in 1989.
