When the project has many geometric objects, this makes MS a little slow to open the first time, this is due to the fact that it reads all geometric objects every time it opens the project in MineSight.
However, you can store a cache memory file to speed up this slow initialization, and all the contents of the folders will be written in txt files. To enable this option, go to MS3D > FILE menu > PROJECT SETTINGS > and check the LOAD PROJECT FROM CACHE FILE ON STARTUP option.
This will make the project start up faster, especially in projects that are networked.
