USG FLEX 50W Configuration Files Cleanup

Hello Forum,

After upgrading firmware and making the necessary changes to the USG FLEX 50W unit, is there a reason to keep the following files:

ezmode-config.conf
autobackup-0.00.conf
startup-config-bad.conf

I wanted to make sure these are not needed for something in the future, or if they can be recreated as needed. Just trying to keep our units neat and tidy. I don't like junk files sitting around forever taking up space unnecessarily.

I do not use easy mode, so that one makes no sense to keep. Just didn't want to wipe it out only to find out later it is needed for some kind of recovery step. Similarly, with the other two, just want to be sure they are not absolutley needed.
