FSEventer: Real-Time File Monitoring
Your Mac has a fairly simple arrangement with Spotlight: in exchange for zippy system-wide searches, OS X lets Spotlight’s indexing agent, mdimport, snack on your CPU from time to time. If you’re beginning to think mdimport is a bit too resource-hungry to make Spotlight worthwhile, fire up FSEventer and be ready for a show.
FSEventer uses Spotlight’s indexing framework to provide real-time, system-wide file monitoring. This means that any time you create, alter, or move any file on your hard drive, FSEventer will register a “file system event” and immediately display the change in an attractive file tree. FSEventer can display up to 80 recent file events, and labels each with its time of occurrence and originating process or application.
