Plugin Storage: Files of older versions? Can they be deletet or not?

Hello everybody,

I have the Adobe Package for photograhers with PS and LR since a few years. I'm using the actual versions fpr windows. Now I found these files on my PC still allocating storage. I think the numbers 22, 23, 24 are old versions and can be deleted. Just to be sure I would like to know if this is correct and I can delete thes folders without any issues.

Thanks in advance!
Best, Dirk
