This is standard 'tar' behavior. There's nothing Cygwin specific here. 'tar's info page has this to say: When extracting files, if `tar' discovers that the extracted file already exists, it normally replaces the file by removing it before extracting it, to prevent confusion in the presence of hard or symbolic links. (If the existing file is a symbolic link, it is removed, not followed.) However, if a directory cannot be removed because it is nonempty, `tar' neither removes it nor modifies its ownership, permissions, or time stamps. To be more cautious and prevent existing files from being replaced, use the `--keep-old-files' (`-k') option. It causes `tar' to refuse to replace or update a file that already exists, i.e., a file with the same name as an archive member prevents extraction of that archive member. Instead, it reports an error. To be more aggressive about altering existing files, use the `--overwrite' option. It causes `tar' to overwrite existing files and to follow existing symbolic links when extracting. The `--overwrite-dir' option is somewhat more conservative than `--overwrite': it overwrites metadata (ownership, permission, etc.) for directories, but removes other files before extracting them.
