Is there a way to search files (logs) being used by another process.

I am using this utility to search log files that are being created and filled up by our windows and web services.
But if i get an error and i try to search this error id in my logs folders the actual log that is being used will not turn up ifts the one containnig the error because i get the Error Accessing File error but that particular log might contain my application error.
I have about 45k logs and 86 logs being accessed and or instanciated so i dont want to have to open each up and have to search for my error id in all 86.

Thank you for your help

I don't have any experience with logs - but have you tried LogFusion: http://www.logfusion.ca/

From the above page:

- LogFusion can also read Event Logs in real-time, and can even use it's powerful Text Filtering and Row Highlighting features to help you find specific items.

- LogFusion can automatically add new logs from Watched Folders. Just specify the folders to monitor, and LogFusion will automatically open any new log files created in those folders.

unfortunately Log fusion does not support folder watch on servers wich is really my need thanks
