Yes, it does.  As it name suggests, it is an internal function, called via 
.Internal, in this case as part of zip.unpack.

How do you know that? (It almost certainly is not: try doing a 
traceback() to find out.)


My suggestion is that you re-install R in a directory without any spaces 
in the path, as that is likely to be the problem.  Alternatively, you 
could install unzip.exe and set options("unzip").
