When running under MSYS2, one must set the MINGW_ROOT environment variable to assist in
determining how to convert Windows paths to UNIX-style paths. This should be the installation path
of one's MSYS2 environment (eg., _C:/msys2_). Go's stdlib, under the hood, still uses Windows
style paths (drive letters and all) to locate other executables and _xc_ uses _tar_ as part of the copy
functionality.
Local (client) to remote (server) copy:
