Defraggler is a free file defragmentation tool from Piriform, the company that brought you CCleaner and Recuva. It differs from other defrag tools on the market, by enabling you to quickly and simply defrag the files you want to, without having to process the whole drive. Simply run it, select the file and defragment in seconds. No more struggling with the Windows defragmentation tool!
And remember like all Piriform products, Defraggler is completely free for both corporate and individual use.
