What is this 20+GB file doing in config?

Today I learned that there wasn’t enough storage for my HA to update and then found a huge file in my config folder. Does anyone know what would generate the following files and is it safe to delete them?

  • HTET93~J : 20 GB
  • HTGVMB~Q : 5 MB
  • H7PRKG~G : 32 KB
  • There are about 10 more with a similar naming convention, they are just 0 bytes.

Thanks!

I think I get those when my database is corrupted. I’ve tried moving them out and all seems fine
