It removes all free atoms and puts moov and tags before actual data.

Edit: this is also described at the statusbar if you hover over the menu item.

sorry, i'm still not sure i understand what this does.  does it make tagging faster as the tag is at the beginning of the file?  does it make the file smaller?  does it make decoding somehow faster?  sorry for the questions, i just never noticed this option in 0.8.3, and i'm not using 0.9.2 beta just yet...

It'll make the files smaller if there is some unused space. There might be also some programs which won't read the tag if it's located after the actual data.

Also, if the atoms are at the end of the file and you share your itunes library, remote itunes clients will not be able to play it.
