Copy file or directory to destination If source is a file, then copyFileTo will be use to copy it. If source is a directory, then more complex logic will be applied:
- if dest already exists and it is not dir, then exception will be raised. - if dest already exists and it is dir, then source dir will be copied inseide that dir with it's name - if dest does not exists, then current directory will be copied to dest path.
Note, that work with symlinks have to be improved. Not tested yet.
