1. Working as root;
2. Suppose you have a directory with sub directries and other files in it (in my particular case, it was a hidden directory, i.e. starting with a dot);
3. Rightclicking that starting directory, choosing Properties, Permissions tab, changing User Ownership, with the "Apply changes to all sub-diretories and its content" option-box checked;
4. RESULT: the ownership of the files in the main directory is changed, but not the onwership of the sub-directories in that main directory.
