So much dlls on strange places

[classic]

I cloned my HDD to a new SSD completely. Just saying, may be it is a valid information.
Everything runs fine.

Now I found this dll´s here on strange places: C:\Users\my user name \.openjfx\cache\18-ea+6



What are they?
Can I delet them?

It's a cache of openjfx, supposedly dropped there by a Java-based program.

Don't mess with things you don't understand. Do you like surprises and/or troubleshooting? Is there not enough free space?

If you want really clean, start with a fresh format. But the next week you have this mess again.
