Be careful with this option, because when you edit a file some
applications (Microsoft Office Suite is the perfect example) create a
new temporary copy of that file, then when you save your work, the
original file is deleted, and the temporary one is renamed to the
original name.
With this option set, the save process fail when the application try
to delete the original file.

PD: Sorry for my english
