This command lets you set up the list of files that LogWatcher watches. They should be apache combined format logs. This will open up a window that lets you browse for a file, and you can choose to read the entire file, or not. If you read the entire file, it may take a long time to parse the file. Otherwise, the last 1000 bytes or so of the file are read. The file will be monitored for changes, and whenever a new line is posted, LogWatcher will parse it.
