my last post was not just about defragmentation. i want to know what sfi.dat is, what it does, etc. does it belong to comodo(cis). if so, when you uninstall cis why is the file not deleted? is this something the developers overlooked? to get back to defragmentation. to me all defragers are built in the mindset of say when windows xp was to about middle age. all defrag stratagies are obsolete given the size of drives today, the number of applications installed and the almost daily updates to many applications. file fragmentation is only one issue. for lack of a better name call it folder fragmentation. lets use the prime folder program files. each application has a folder under this. over time the files for an application get spread all over the disk. this causes just as much head seeking as file fragmentation. consider that a lot of people on a regular basis do a clean install of windows and then re-install all of their applications. their hard disk is then in the most possible perfect state. it would be nice to have a defrager/optimizer that could do this. all files that belong to any prime folder would be together. all files for a given application would be together. after that would come personal optimization which is a tale for another day.
It seems that nobody knows what sfi.dat is or where it came from- I don’t think I had it until I got v3.9 though.
Solution “Use Puran Defrag”
Puran Intelligent Optimizer - PIOZR
Directories Consolidation for speed boost
Optimization by Freeing Space
Automatic Defragmentation for worry free defrag
Boot Time Defragmentation for system files like MFT
Low Priority Defrag for work while defrag experience
Individual File/Folder Defrag for selective defrag
GUI and Console Command Line Defrag Supported
Restart/Shutdown After Boot Time Defragmentation
File/Folder Exclusion or exclusion by wildcard facility
Native support for 64Bit Windows
Supports Windows Xp/Vista/2003/7
I use MyDefrag (new version of Jkdefrag)
I didn’t like JkDefrag. I use Auslogics and every so often run the XP defrag afterwards to compact things more. CIS gives me no problems doing defrags.
I was wondering if Mydefrag and Jkdefrag would come up. I use Mydefrag because it seems to be faster than the defragmenter with Vista.
Might i ask why you didn’t like Jkdefrag? Is there anything i should know about it maybe? Screwing up my harddrive maybe? Just curious.
I use JKdefgGUI, http://www.emro.nl/freeware/ which is a very nice front end, and provides easy access to some of the more powerful features of JKDefrag.
There is a new version of this for MYdefrag. Hopefully be released soon.
I found JK defrag to be no faster than the XP one. It also kept moving my large game files to the end of the drive and calling them “Space Hogs” which actually made the process take more time than the built in XP tool and seemed to make the games load slower. Auslogics is blazingly fast but presently offers no file placement optimization features. I like it however. If you want a fast defragger that has optimizers, you might try SmartDefrag from Iobit. (it didn’t work right for me, but a lot of others swear by it and it’s free)
I use JKDefrag and now upgraded to MyDefrag.
MyDefrag is more powerful than JKDefrag as you can now write scripts to customize optimization method.
For example, you can just defrag without file placement optimization or perform file placement optimization for a specific group of files only. Dch48’s problem can also be solved by excluding the game files from “Space Hogs” list.
I have no idea how to write scripts and having to do that in any program is pretty bad design imo. JK /MyDefrag is way too slow for me, PerfectDisk should be renamed ImperfectDisk, and the optimization routines in SmartDefrag scatter my files all across my disk with huge gaps in between. I’ll stick with the combination of Auslogics and the built in Windows tool.
I agree that it may not worth to spend the time to learn the scripts.
It’s just all about personal preference and interest. 
I sujest you try ultimatedefrag, it depends all on how YOU would like your harddrive
