    Unmovable Files (XP Pro)

    When you use Windows Defrag or Nortons Optimization why are there unmovable files , ( You know the ones in red)? I have already moved my Page Files & Temp Files to a different Partition. It seems to me if you have files that are not moved it would not be making the best use of that drive. Is this wrong or right. If so what can i do to get them to defrag or move ?

    Often these are files in use, or system files that for security reasons can not be moved. I believe the way a defragger works is to first make a (defragged) copy, change the address of the file to the new position, then delete the original. If the original is locked, it can not be deleted and the defragmentation of that file fails.
    I find I get best results by minimising the number of applications running, and running a defrag immediately after logging on.
    Also logging on as another user releases any files specifically locked by/within your own profile.

    I also find I get best results by using Diskeeper.

    Many people suggest running a defrag in safe mode so there are the fewest possible files in use.

    Diskeeper also gives you the ultimate option of a boot-time defrag when absolutely nothing is yet running. This allows defragmentation of page file(s), the MFT etc.....

    Safe-mode defragging isn't necessary in Windows NT/2000/XP (and isn't an option in NT) because of the way the file system is designed. Diskeeper can defragment the drive while it is in use, with the exception of the MFT and paging file. It will put a hit on performance while running, simply because the disk is in constant use, so if you don't like waiting for windows to paint and dialogs to open, don't use the PC while Diskeeper is running.

    I had the same experience with OO Defrag and Raxco PerfectDisk as well, but I felt their products couldn't hold a candle to Diskeeper - and Executive's support team left most other support divisions leagues behind.

    Don't worry about the files that aren't being moved too terribly much. Chances are that they are not affecting your performance in any noticeable way. Further to Leif's explanation, those files are usually present on NTFS drives, and can consist of the Master File Table, the swap file, directories, and Metadata. These items are not moved during a normal defragmentation run because Windows opens the files for exclusive use and locks them - if you have ever run a disk check and told XP to automatically fix errors, you know what I mean. Windows has to reboot so that it can check and correct certain problems.

    The whole idea with defragmentation is to reduce the little bits and pieces of data scattered about and organize them into longer, contiguous blocks. The more fragments a file is in, the longer it will take to read in to memory, because the hard drive's heads must perform a separate read/write operation for each fragment. NTFS is exceptionally efficient, FAT32 less so - but due to the design of XP, fragmentation doesn't affect you in a tangible until it gets bad.

    Does that help any? <img src=/S/smile.gif border=0 alt=smile width=15 height=15>
