Layout.ini and prefetching


Tester1

Recommended Posts

Hi Tester1,

 

Well, we discussed Layout.ini, prefertching in Think About Defragmentation thread. It is what Windows is doing to determine

where and which files to put when defragging every three days, three starts according to user's usage of the programs. (Command window "defrag C: -b")

The discontinued MS BootVis program is exactly analyzing and applying these.

 

I don't think SD is using that. (I am almost sure)

The main reason for automatic application (Reg value=1) of "NtfsDisableLastAccessUpdate" by AWC, and ASC must be this.

 

Cheers.

PerfectDisk and the layout.ini file??

 

I don't know the technical information behind this, but PerfectDisk does something with the layout.ini file in the C:\Windows\Prefetch folder when defragmenting; I posted a link with this information in an earlier post. Does anyone know the technical information about layout.ini and how it can be used by 3rd party defragmenters like SmartDefrag?

 

I know that Windows XP uses prefetching to improve boot and application loading times. All "tweaks" about prefetching are fallacies - source:

(Scroll down on that page a fair bit and read the section on prefetching.) If your have tampered with prefetching, I recommend you use the "Prefetcher Fix" on this page, as instructed:

http://home.comcast.net/~SupportCD/OptimizeXP.html#Tweaks

 

Maybe another feature that could be added to SmartDefrag is to check the Windows Prefetch settings are set at their correct default values, if they are not, SmartDefrag could offer to fix this and reboot. Anyone agree? We are trying to make Windows run FASTER aren't we?

 

Cheers.

Hi Tester

Two very good informative links! Thank you!

Take a look at this post http://forums.iobit.com/showthread.php?t=509&highlight=prefetch and read Claytons warning.
