    File fragmentation (XP PRo (SP1))

    This is probably a silly question but I'm wondering whether it is possible to 'unfragment' individual files. I have a drive for data and even after defragmentation the report is showing that total fragmentation is 23% and file fragmentation is running at 47%. My idea is to defragment another partition and then copy the files to the new partition and defragment that partition again. I'd reformat the original drive and then copy the files back to their original drive. Would this improve matters or is it just a waste of time?

    Thanks,

    Chris (Hunt)

    Hi Chris,

    You don't say what defrag program you are using, but I suspect it's Window's native defrag utility. I never did care much for that (too slow and an incomplete job of defragging). I use Perfect Disk by Raxco and believe it to be the best available solution for XP systems. It's fast, through (it even defrags your page file) and if you let it do it's work at night while you sleep (I have it scheduled to run every night), you'll never know it's there except that your system will be running at optimal performance most all the time. I used Diskkeeper for a couple years and thought it was a great product (and it is) until I discovered PerfectDisk. I'd skip the partitioning and just grab a copy of PerfectDisk. Just one man's opinion though.

    I second the recommendation for PerfectDisk! I followed the same route you did, Doc and have been more satisfied with PerfectDisk. Every couple of months, I have it also do a "boot time" defrag which seems to get the defragging a little tighter.

    Al,
    I've been so pleased with the way my system performs that I had never run a Boot Time Defragmentation Pass. Of course I run my system 24 / 7 and only reboot when I have a problem or feel the system is performing less than optimally. I read the section on Boot Time Defragmentation in the Getting Started Guide (see attached zip file) and think I'll give it a try this afternoon.

    BTW - How did you get your signature to display that way ??? Very Cool !!! <img src=/S/thumbup.gif border=0 alt=thumbup width=15 height=15>

    Re: File fragmentation (XP PRo (SP1))

    Isn't it funny, the habits we get into? I've been warm booting my system every morning ever since the days of Win95. Back when Win95 and Win98 were the principal single user OSs, there was all this stuff about memory and resource leaks, that I got into the habit and still do it to this day, even now that I run XP Pro. I've never tried to document or prove it, but I still think that some applications don't "give back" memory or resources the way they should. Sometimes after a day of heavy surfing or doing graphics work with lots of pictures (PSP) I'll notice or imagine some slight sluggishness, so I reboot every morning and sometimes more.

    To answer your other question, I took the one-frame static GIF and using PSP made FIVE equal size GIFS out of it, blanking out letters in each one. I then used the simple little Animation Shop app that comes with PSP to create the animated GIF strip shown in the attachment. I varied the timing of each frame but haven't yet really "optimized" the file.

    It has been documented and proved that XP can behave this way and "leak" or run with some programs not giving back memory, of course not as often and consistently as Win 9X in general and Me in particular did, so you are probably helping your performance consistently when you do this.

    Without enough free space on a drive, the defrag program will not give you a perfectly defragged drive. It needs room to juggle files around while it is defragging.

    Although the theory of disk defragmentation is fine and/or dandy, I've still to come across a non-pathological case(*) on a (fairly recent) workstation (not a server!) where anyone was able to demonstrate that there was a significant difference "before" and "after" a defragmentation run. I'm not talking about (say) Windows for Workgroups 3.11, where failure to keep the disk tidy could cause the operating system to stop (yes!), but Windows NT upwards for the average "office user". I realise I may be talking heresy here (certainly in Diskeeper's and Perfect Disk's eyes <img src=/S/argue.gif border=0 alt=argue width=50 height=25> ), but I speak as I find!


    (*)The pathological case I'm talking about was an absymally-written database program which created many thousands of pairs of files, one 'permanent' and the other temporary, and then deleted the temporary ones, which were interspersed among the permanent ones. A couple of months of running of that program daily caused the most amazingly-fragmented disk <img src=/S/dizzy.gif border=0 alt=dizzy width=15 height=15>, which it took well over a day to defragment. Most workstations don't do this sort of thing, and NTFS copes fairly well with most usual forms of usage.

    Windows disk defrag utility requires at least 15% free space to effectively defrag the drive. Perfect Disk works fine with just 5% free space. This is the reason that the Windows defrag utility is so inefficient by comparison.

    Doc

    The Windows XP defragment utility is a rather crippled version of Diskeeper, which also quotes a "15% free disk space" limitation...!

    Al,
    First, thanks for the mini-tutorial. <img src=/S/smile.gif border=0 alt=smile width=15 height=15> I'll definitly be playin' with that one. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    As far as the memory loss / leak / not give back issue, I've been using a neat little utility called "Free Ram" that runs in the background, is highly configurable, can be operated manually and keeps the free RAM on my system at a very high level. I have 512 MB installed and usually run with about 275 - 300 megs free. If an application is pulling down the free RAM, I just click on the icon in the SysTray and tell Free RAM to try to free 90% of the total RAM. That will ususally bring me back to 250 - 275. I've forgotten where I got Free RAM from, but will check it out if you're interested.

    John,
    Have you tried running Perfect Disk on that "problem" workstation ??? The reason I ask is because I have noticed a significant change in performance immediately after running Perfect Disk on any system. I just reconfigured a laptop for a friend and after I finished all the uninstalls, installs deletions and changes, I installed and ran Perfect Disk on that machine because it seemed to be dragging. Perfect Disk took about 10 minutes to do a 9GB drive with 50% free space and it was running like a champ after the defrag. The windows literally snapped open and it just felt crisper and cleaner. IMHO, of course. <img src=/S/yep.gif border=0 alt=yep width=15 height=15>

    Doc

    Sorry, that was a historical workstation, about five years ago! The system got binned because it was a) horribly written and [img]/forums/images/smilies/cool.gif[/img] not very useful! We had to look at it before the decision was taken to scrap it...
