    Hello,

    I'm surprised and don't understand why i get different result between the udefrag.exe and the defrag.exe about the fragmentation analysis.

    So check what i done :

    Command : udefrag -a -v C:\

    Results :

    C:\
    C: analyze:  100.00% complete, fragmented/total = 0/74935
    
    Drive information:
    
      Total space                  = 195.26 GB
      Free space                   = 182.42 GB
    
      Total number of files        = 74935
      Number of fragmented files   = 0
      Fragments per file           = 1.00
      Fragmentation                = 0.00%
    

    Command : defrag -a -v C:\

    Results :

    The operation completed successfully.

                    Total folder fragments      = 8

                    MFT size                    = 70,50 MB
                    MFT record count            = 72191
                    MFT usage                   = 100%
                    Total MFT fragments         = 2
    
            Note: File fragments larger than 64MB are not included in the fragmentation statistics.
    
            You do not need to defragment this volume.
    

    Why udefrag.exe report there's 0 fragmented files and defrag.exe report there's 65 fragmented files.

    If someone could explain to me

    Thanks

      We would need to know which files Windows defrag did mark as fragmented, but this information is not available.

      For udefrag, there should be a log file as %UD_INSTALL_DIR%\Logs\udefrag.log, if you could attach that, we would at least be able to know what settings might have been causing this.

    Thanks for your reply.

    Unfortunately, i don't have any udefrag.log in my C:\Program Files\UltraDefrag\Logs but only a ultradefrag.log.
    For your information, i didn't defragment my hard drive but only made some analysis (-a -v). Perhaps i should defrag one time with udefrag for get
    a log file ?

      No need to defrag, just set the UD_LOG_FILE_PATH variable before analyzing.

      See the handbook/help/manual => Reporting Bugs => Collecting debugging information to report problems using the console interface.

    ok i done it.
    Check it in the attachment.

    Btw, I done without "set UD_DBGPRINT_LEVEL=DETAILED"

    Thanks.

    dfrgui.exe on Windows 7 really sucks now o.O

      Thanks for the log, I have now found the problem.

      You are using the command line udefrag -a -v C:\ , which only scans the root folder of the C drive.

      To scan the whole c drive use one of the following command lines:

      udefrag -a -v C:
      
      udefrag -a- v C:\*
      

      The first one is the most commonly used one, the second is the one that checks the contents of the specified folder.

    ohhh nice :)

    As you can see, it's better yeah ! I'm happy now and sorry for that, it was simple but i didn't find by myself :( :(

    Result :
    C: analyze: 100.00% complete, fragmented/total = 447/78852

    Drive information:

    Total space = 195.26 GB
    Free space = 182.10 GB

    Total number of files = 78852
    Number of fragmented files = 447
    Fragments per file = 1.00
    Fragmentation = 3.40%

    Thanks Stefan

      Sorry for the late reply, have been busy and got a bit ill recently.

      The fragmentation report saved to C:\fraglist.luar will list all fragmented files.

      From the GUI window you just select the report action (F8) to display it.

    Can someone tell me where to find the ultradefrag for 64 bit windows. All I keep coming up with is the 32 bit one. My puter won't use it. I'm rather dumb about most things computer so please make any directions super simple.
