File System Events are saved permanently in the Main Window until you remove them. They are saved even when you quit Sonar. To remove events, select them in the list and click Delete Items. To remove all items, click Clear All Items....
You can click Add Flag to add a red flag entry to the event list. This can be handy for marking special times in the list. For example, you might add a flag right before installing a new program, and right after the program finishes installing. The events between the two flags will be the events that took place during the installation.
You can use the controls at the bottom of the window to search for specific events. Several search options are available. If you have purchased a license, you can turn on Show Hidden Files. This feature is only available if you purchase a license. Many temporary and utility files are set to be hidden in the Finder, but Sonar can show you when they have been changed if you turn on this option.
To copy events, just select them in the list (use the command key or shift key to select more than one) and drag them to the desktop or into a text editor. The text that is dragged out will be tab-delimited and will contain complete file paths. You can also copy selected events by choosing Copy from the Edit menu.
Sonar stores the event log in a database file in your preferences folder. The event log is saved automatically every 2 minutes and when you quit Sonar. If you want to save the event log immediately, choose Flush events to disk from the Events menu. The event database is compacted any time you click Clear all items.... If you want to compact the database by hand, hold down the option key and choose Compact Database from the Events menu. Every time you save or compact the database, you will generate file events that will appear in the Sonar list.
If you check the Auto-Scroll checkbox at the bottom of the window, Sonar will automatically scroll the list to the bottom every time a new event is added to the list. You can turn this off if you want to browse upwards through the list without having the scroll snap down again every time a new event arrives.
You can click an event in the list to select it and display the path to the affected file. If part of the path is truncated, just point the mouse at that part to see the complete name. You can click the path display to reveal the affected file in the Finder (if it is visible and not deleted).
