Find a “tail” cmd-line program like “tail-f” or “WinTail” (gui) and load to your c:\ path.
I’ve been using tail for windows by TriSun Software Inc. and does the job fine and its FREE!

Typical usage: [bash]c:\tail.exe -f c:\myfile.log #log the whole file
c:\tail -f -10 myfile.log #log the last 10 lines of the file[/bash]

You can also pump the last 10 lines of one file into another one:
[bash]c:\tail -10 “c:\myfile.log” > c:\myfile_10.log[/bash]
