I have problems in reproducing the scenario. Coul you, pls, give
examples of PATH-LOCAL and PATH-REMOTE?

It is also important to know, whether PATH-LOCAL is an existing file or
directory. Also, in case of a directory, it is important to know,
whether the string PATH_LOCAL has a trailing slash.

Thanks, and best regards, Michael.
