If you are working with a per user workspace catalog, you can create a starter set of palettes and tools for the project users by copying your palettes to the project tool palette file location. The first time a user opens the project, the tool palettes from the tool palette file location will be copied to the local users’ machines.
If you have just closed AutoCAD Architecture, the current project folder is the one with the latest date. In addition, the folder is named with the project GUID, which you can also find in the project APJ file.
