HzTail is a WinTail. It is a real-time file viewing Windows utility 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, as they are generated. Quickly viewing the last part of a large file without the need to load the entire file.HzTail is a file viewer. It makes no changes to the file that is opened. It opens the file in read-only mode. As new lines are written to the file by another program (such as would happen with a log file, for example), HzTail reads the new lines and displays them.
