Question about IObit SmartDefrag


Recommended Posts

Hi Tester1

Please read the whole of enoskypes string "Think about defragmentation"


it will give you a lot of answers and insight.

Have a nice read :-)






I'm just wondering if SmartDefrag will defragment the system files too? I'm using Windows XP Home Edition. If it does not defragment system files, must you run PageDefrag BEFORE running SmartDefrag?


Please advise.

Good advice solbjerg,

Hi Tester1,

Addition to solbjerg's advice, short answers to your questions:

Smart Defrag does not defragment excluded System Files.

PageDefrag defragments the Pagefile.sys.

If your Page File is fragmented, then running PageDefrag before Smart Defrag is better for Optimization.


My advice would be to use the trial version of PerfectDisk once for "Offline Defrag" (all system files defragmentation including Page File), and then use Smart Defrag.

Can SmartDefrag do the same?


Why not make SmartDefrag do an offline defrag of the system files, paging file, registry hives etc – everything that PageDefrag does?


Besides optimising the paging file, it needs to be placed on the optimal location on the disk, some people say it's faster placed exactly in the MIDDLE of the disk and others say it's faster placed at BEGINNING of the disk, unfortunately I don't have the page sources to prove what I'm saying. :evil: Also, can the system files be placed at the beginning or other area of the drive to massively increase performance?


If SmartDefrag is to match its commercial rivals, it needs to perform an offline defrag of ALL the system files that it can't touch when Windows is running.


As for the paging file fragmenting, this can be avoided by setting both the initial and maximum size to 3x the amount of RAM memory installed (up to 4096MB in Windows XP, I'm not sure if that applies to 64-bit versions too). However, you WILL need to alter these amounts if you change the amount of installed RAM in future. After changing these values and rebooting, you will only need to defragment the paging file once, unless you change the settings in future.

Also, placing a second paging file on the FIRST partition of a DIFFERENT internal hard disk will increase performance, as well as having the first copy on the boot partition (source).
