How can i rename the log file with Modified date by using Rolling Flat File Trace Listener

Question

My desire output is, if "rolling.log" file was created and modified by 26-06-2012, next day(27-06-2012) that file should be renamed with "rolling-26-06-2012..log". Now output is "rolling-27-06-2012.log" file.

Below is my current logging setting in web.config file.

<*loggingConfiguration name="" tracingEnabled="true" defaultCategory="myTestLog">

Unfortunately this is the way it works in Enterprise Library. The philosophy behind its default flat file roller is that it records all the output in FILE.LOG and when the roll event happens, it renames it to FILE-ROLL-NAME.LOG and creates a new FILE.LOG If you need a different behavior, you may need to create your own logging trace listener or use other tools out there like log4net.
