Alternative of iDefrag to remove fragmented data

Many Mac user's complains through various forums that ,with the passage of time ,Mac system starts slowing down and it affects their work.. We suppose every file is saved in continuous memory block on the Mac disk but, in case of low disk space , large files divided into several chunks and there are not much contiguous spaces available to save these files . Many files on the disk splitted into several pieces and scattered over Mac disk. When we open those files , processor takes long time to pick up each fragments and open it. 

There are no any inbuilt defragmentation tool available in Mac like Stellar Drive Defrag ,iDefrag etc.. Stellar Drive Defrag is a famous defragmentation tool of Stellar.
