From everyone here at Piriform, the company that brought you CCleaner and Recuva... we now bring you a file defragmentation tool... Defraggler!
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.
I have been using it, and its really a neat program. Its still v1.00 (BETA) but I have not had any issues on XP SP2. Plus its free!!!
