Conceptually, I think the difference is that on unix-like systems, the
ability to create and delete files is controlled by the permissions on
the containing directory. If you have write access to the directory,
you can delete a file regardless of the file's permissions. On windows,
where your files actually reside, I think you must have write permission
on the file itself - but unless this is set explicitly it would be
inherited from the directory above.
