Even with Filters and Custom Views to help you sift through an event log, there can be so much old data in a log that it gets cumbersome. You can save yourself time by using Event Viewer’s Save and Clear feature.
To do so, select Clear Log in the Action panel. When you see the Event Viewer dialog box, click the Save and Clear button. In the Save As dialog box, enter a descriptive name and select any one of the available file types.
