FileAlyzer is a Windows utility from the makers of Spybot Search & Destroy, which provides you with all sorts of information about any file on your computer. Once you install FileAlyzer, just right click on any file and click the Analyze with FileAlyzer button to see detailed information that goes far beyond the usual size and last modified date.

The utility can display the contents of archived files, display audio tag information, and a whole bunch of other information that I'm not smart enough to understand.

The latest beta version of FileAlyzer adds the ability to analyze multiple files in one window.
