Suddenly... .fseventsd, .TemporaryItems, .Trashes and LOTS of others appear in ALL the disks

Hello, group.

That's it. Somehow, lots of these "zero bytes" files appear on ALL the disks, when I open them.

I've read this is due to Spotlight, even if I don't use this feature. These are files that should be invisible, right?

What did I do wrong?

I add an image of the annoying aspect of the System HD.

My OS is 10.15 Catalina

Thanks to any tips to get rid of this thing
