Hoo WinTail is a real-time log viewer for Windows like the UNIX tail -f utility. It can be used to view the end of a growing file. It is ideal for viewing application traces or server logs in real time. You can view the last part of a large file without the need to load the entire file quickly. It can capture and display OutputDebugString (Windows Debug API) and TRACE / ATLTRACE (MS Visual C++ Debug Macro) output as well.
