Yes, Emacs probably uses that binary. You should see a message to that effect in *Messages*. How does it know? it looks along your PATH to find the executable it needs. > If ezwinports is the source of bzip2 for Emacs, I don't see similar > gzip utilities, so I'm quite confused. You should be able to find a Windows port of gzip on the GnuWin32 site: http://gnuwin32.sourceforge.net/packages/gzip.htm AFAIK, that's what I'm using; never bothered to port a newer version because that one does a good-enough job for my needs. (But of someone points out why newer versions are so much better, I might be tempted to provide their binaries.) I'm quite sure there's a 64-bit port of gzip available from the MSYS2 site, but you'll have to find it yourself, or maybe someone else here could post a URL.
