offline defragmentation & reg optimizers

[thunderrooster]

Hi. I was wondering if disk defragmenters like perfectdisk, diskeeper, etc.. defrags the registry hives. Do they defrag everything that PageDefrag does? Is NTREGOPT and RegCompact.NET the same? I see that both compact the registry. It seems like RegCompact.NET does more though.

RegCompact.NET solves the problem of registry fragmentation and large size by rewriting the registry hives into new files which are optimized and often much smaller. Your computer is restarted after the registry hives are compacted and during system startup the old, fragmented files are replaced with the newly generated and optimized ones

I do not think that is defraging the registry though. From what I have looked up the only thing that will defrag the registry is PageDefrag. Am I right? lol. I was looking for a program to do both defrag and compact the registry. Once I started looking some say disk defragmenters does defrage the registry hives and some say they dont so any help appreciated.

Microsoft's defrag APIs (which all defragmenters use) support defragmenting registry hives (ensuring the file file as it exists on the drive is in 1 piece). However, even though the defrag APIs support it, not all defragmenters take advantage of this ability. Most of the commercial defragmenters take advantage of this feature. Reg optimizers (in my opinion) cause way more problems that they cure. Why they may recover space on disk by compacting the registry, they do not actually specifically defragment the registry (ensure that the file on disk is in 1 piece).

Hello GHayes - you & I have "collided online" before, & I read your statement about "Registry Optimizers" & them causing troubles... well, I guarantee thsi one does not:

I didn't make the mistake other registry cleaners do/did, & that is:

MOST of them tend to expose CLSIDS (class identifiers - a registry based entity) &/or TypeLibs (both registry AND disk based entities) as valid candidates for removal by end-users, who most likely do NOT know how they work...

In other words, blow the wrong one of those? Don't wonder WHY things in your OS &/or APPs stop working!

(Mine filters vs. those & you never get problems from it because of that).

P.S.=> By the by, nice seeing you around again man... apk

From Systernals:

PageDefrag uses advanced techniques to provide you what commercial defragmenters cannot: the ability for you to see how fragmented your paging files and Registry hives are, and to defragment them. In addition, it defragments event log files and Windows 2000/XP hibernation files (where system memory is saved when you hibernate a laptop).

From NTRegOpt:

NTREGOPT is not a Registry defrag, it removes empty space/slack in the registry & returns the bytes back to general use.

Note that the program does NOT change the contents of the registry in

any way, nor does it physically defrag the registry files on the drive

(as the PageDefrag program from SysInternals does). The optimization

done by NTREGOPT is simply compacting the registry hives to the

minimum size possible.

All-important:

• Aplications like Free Registry Defrag, Auslogics Registry Defrag, RegCompact.NET - don't defrag paging files/Registry hives/hibernation files.
  
• JkDefragGUI can do that: it use NTRegOpt, firstly, to compact and PageDefrag to defrag paging files/Registry hives/hibernation files.
  

I use JkDefragGUI: useful, excellent and... freeware....
