<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Thanks! Inspired by that I dug a little deeper and it seems autoexpire.cpp uses GiB (1024-based) which makes sense, but I needed to verify that since the UI says GB.</p>
