they are probably used to open your pdf files faster, see how long it takes to open a big pdf after you remove them all, then see how long it takes on subsequent opens.

if you have plenty of ram make a ramdisk and create a symbolic link of that directory to the ramdisk, then they all go away when you shut down.

If this is an SSD, then I would definitely do that to save on wear and tear.

Thanks to all who responded re my okular question.

I conclude from the responses that there would be no
harm done by deleting all those files. So that answers
the most important part of my question. I'm still curious
why those files are created in the first place and what,
if any, benefit they have.
