Regapp ID Cleanup Utility for AutoCAD 2021-2025

Autodesk Support

May 26, 2023

This utility removes excess unreferenced registered application (regapp) IDs from multiple files simultaneously.

When you delete an object with Extended Entity Data (xdata), a regapp ID remains in the application ID (APPID) symbol table. When a file contains excess unreferenced regapp IDs, performance may be negatively affected.
