Where is the Error Log Filename? [SOLVED]

Hi all people...
I want to know where OC stores the Error Log Filename from the System/Settings/Server tab if the name is set like
* Error Log Filename: error.txt
I can't found the file in the Linux Ubuntu file system...
Can somebody help me on this?

Ok, I found where the error file will be stored.
<store_home>/system/logs/error.txt
Hope this help somebody...
