SharePoint 2007 Log Folder Location

Default log location for MOSS 2007 is "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\LOGS"

To avoid unnecessary burden on the Operating System (C:) drive, SharePoint Administrators often use the best practice of moving logs to a  different Drive/Location.  The following are the steps to change the default SharePoint Log location:

1. Login to Central Administration website.
2. Navigate to Operations menu. Under the Logging and Reporting section, click on Diagnostic Logging option.
3. Under the Trace Log section, provide the new Path of Log file.
4. Click OK to save the settings
