The ULS Log Reader was built to make working with the new ULS logs found in SharePoint 2007 more manageable.  All you need to do is select the directory where your ULS logs are found, and Log Reader gathers a list of all the ULS logs it finds there.  You can then open any of the log files and review the content in them in a much more readable manner.

You can also sort all of the data in the logs, and as you select each log entry the details are displayed in an easy-to-read format in the log reader.  You can also select one to many rows of log data and copy it in simple format to the clipboard.  You can copy it as descriptive text, or in a format that you can use to paste into Microsoft Excel.  The built-in sorting and copying make it much easier to find the information you need in your ULS logs, and easily read through the details of each entry.

Finding Information

ULS Log Reader has other ways as well to try and make it easier for you to track down important information in the logs.  To begin with, there's a complete filtering system built-in for all key fields:

This allows you to set filters on one or many fields, and within each field you can filter on one or many values.  You can also search within the log file to look for specific words or phrases using the Search box.  ULS Log Reader gives you lots of visual cues so you know exactly what you're looking at:
