StepTree is basically a Tree-Map extended into three dimensions where the size of files and directories is mapped to area in the visualization. Thus the area of a directory in the visualization is an aggregate of the sizes of all its descendants (subdirectories and files)."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
