You may find various defrag programs in the market, they may look the same, but many of them lack of ability to effectively defrag all the MFT (Master File Table), they will automatically skip certain system files with extensions such as DLL, INI, COM etc during the defragment thus left remnant fragments after each defragment action, it can also easily get halted while defragging which is very user-unfriendly.
