How to Add rsync to Git Bash for Windows 10
Download the package: http://www2.futureware.at/~nickoe/msys2-mirror/msys/x86_64/rsync-3.1.2-2-x86_64.pkg.tar.xz
Extract it and move rsync.exe
to %HOMEDRIVE%%HOMEPATH%\AppData\Local\Programs\Git\usr\bin
.
Thanks @timmy-ly,
I edited the it a bit. Copy four libs to the same folder, and extract them all, then copy the "usr" folder to "C:\Program Files\Git".
