Thank you for your reply.
It's good that you can fix 2D or 3D functions by inserting keywords into folder or file names.
Considering user convenience, it's more convenient to turn the function on and off in the settings menu than to insert keywords one by one into folder or file names.
One of the reasons for the delay when moving to the next page in SKYBOX seems to be caused by the parsing to automatically distinguish between 2D and 3D. If the above function is introduced, it seems that it will help improve the speed to some extent.
Sometimes, I install other VR players and look for alternative apps because of this small feature.
