But they have this item that they consider as a beta, that I first saw at majorgeeks - now the newer beta is at filehippo. It's full name is piriform's defraggler. I have a WINXP Home Edition with a 37.27 GB of space that can be used from my 40.01 WD HDD. I didn't results with others but the Beta?? I had 87% free space, ran the first one and how at 88% free. This is where it got interesting, I had deleted some items that amounted to appx. 1% more but now have 90% free space. It does list numbers of fragmented files and lists all the items on a page. Put checkmark in the first and up to defrag C: on the first item - no dirctions but easy to understand. Looks like the old type defrag with the blocks but that is only a small part, that list is impressive! You can actually see if ther items that are no longer needed; I saw system volume informatmation\_restore (System Restore. It claims that it will work for up to Vista 64 bit. Now, seeing beta, I kept thinking that this will improve?? That was over 8 GB reclaimed! the thing I wasn't sure of was the numbers my drive is listed as 37.3 GB then realized that the 10ths were geeting rounded up/down - I learned tht in school. .00 to .04 read as .0; .05-.09 was .1! It was accurate!! But the real kicker is that I can turn off Sytem Restore and use Ad-Aware 2007 on a short run and set one restore point after setting thst to 200MB. Needless to say, I wonder what thr finished defraggler will do? Oh, you may ask what about the Vista built-in utility? My response is what about the WINXP built-in utility?? If it can improve that well... any inelligent person can answer that! Now, I did run up a WIN98SEdefrag that didn't get past 10%, so I went to Safe Mode and got 100% defrag!! I am tempted to see if I can get those 20 squares tighter still, in safe mode. Darrell
