What is the point to specify 'Enable Log File Rotation'?

[gawa]

My question is regarding System Settings=>Controller=>General=>Logging.

I'm wondering what is the point to specify 'Enable Log File Rotation'?

In my understanding, just having to specify "File size(MB)" will automatically generate archived log files in specified size like this.

2025-03-01_1.csv (10MB)

2025-03-01_2.csv (10MB)

2025-03-02_1.csv (10MB)

2025-03-02_2.csv (10MB)

...

Active_Log_FIle.csv (3MB)

So the below description about 'Enable Log File Rotation' seems already met regardless of selecting/deselecting this option.

I'd like to know what kind of difference selecting/deselecting this option will make. 

Select Enable log file rotation to place log files that exceed the max size in an archive file. 
New events write to a new file. 
This prevents the creation of large log files that are difficult to consume in standard log readers.

I've checked some resources but I can't find exact answer so I'd like to ask for your help on the subject topic. Thank you in advance!

Sorry for self-solving post. As far as I tested with experimental Server, I understand its behavior as follows:

1) 'File size' is applicable only when 'Enable Log file rotation' is enabled,

2) When 'Enable Log file rotation' is disabled, a single log file is generated and growing unlimitedly regardless of specified value in 'File size'.
