I've heard that it is not constant, but I don't know the circumstances where it changes. If your test case my computer asks me if I want to overwrite the original file (edited for brevity): C:\test>copy con testtesttest.txt ^Z 1 file(s) copied. C:\test>dir 10/23/2006 03:21 PM . 10/23/2006 03:21 PM .. 10/23/2006 03:21 PM 0 testtesttest.txt 1 File(s) 0 bytes 2 Dir(s) 989,495,296 bytes free C:\test>dir testte~1.txt 10/23/2006 03:21 PM 0 testtesttest.txt 1 File(s) 0 bytes 0 Dir(s) 989,495,296 bytes free C:\test>copy testtesttest.txt testte~1.txt Overwrite testte~1.txt? (Yes/No/All): n 0 file(s) copied. So it remains the same in this case. My understanding is that it remains the same in all cases except during certain copy operations, where the LFN is copied, and when the file is created at its new location a new SFN is created which may or may not be the same as the old SFN. -Adam -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
