Lucky for me that it wasn't a critical file, but next time it might be.
I have experienced many bugs with Explorer in Vista and have read about
many others (including issues with copying large directories).
I'm not saying it was an Explorer related issue. Not once have I had an
experience as described in my original post in my years of computer use.
For a file to just vanish into thin air is a mystery to me. My system is
clean of malware. Even if it was a virus there would usually still be
some trace of the deleted file.
I just thought there may be others in this newsgroup that have
experienced something similar.
