Understanding log action for disk

Can I just check I understand these settings that I’ve just enabled. It’s currently writing to log 0.txt. When this reaches 1000 lines, it’ll start writing to log 1.txt. When this is full, it’ll overwrite log 0.txt?

Not exactly. It will rename the current ".0" to ".1" and start a new ".0"

With 3 files, it would rename ".1" to ".2" and ".0" to ".1", then start a new ".0".

Thanks, makes sense that .0 is always the latest and old ones are 1, 2, 3 etc.
