What are log file size or time limits?

[advda]

Imgbrn 2.5.8.0 Win 7 64 bit

I just noticed that Imgbrn log file approximately 500 kB has lost 4-5 month old info.

What is the size or time limits to follow making backups of logs?

I'd like to keep earlier logs as these contain writer and write speed info.

 

Thanks.

There is room for about 5000 lines if I remember correctly.
