    Dear Sirs: I had been using system ninja for the past 3 years without a problem. Just downloaded your new version 3.0.3 and found that after scanning 2625 files it freezed and then just stop working and finally close itself.

    Can you give me any suggestion on what to review or set in my pc to make it work properly?

    Many thanks.


    Options – Settings – Run in “Debug Mode”. Reproduce the error. Put on a forum logfile.


    My Ninja 3.0.3 also freezes and always after checking 91% of the files. Normal mode or debug mode makes no difference, Ninja has to be terminated “by force” and no error report is given. Only drive C: or only drive D: or only drive E: or all drives in one go makes no difference. My system: Windows 7 Pro 64. Previous Ninja worked fine. CCleaner runs fine. No faulty drive, corrupt files or other mishaps.


    Problem with Ninja freezing is solved ! The map C:\user\local\temp was filled with almost 60.000 files. Once deleted Ninja works fine !

    That’ll do it.

    Sometimes if the scanning thread is finding files and sending them to the UI thread too quickly, the UI thread becomes overwhelmed and causes the application to freeze. Looking into a method to prevent this.

    Here is the report after running system ninja in debug mode:

    Exception encountered in module [System Ninja]
    Message: Actualmente, este BackgroundWorker está ocupado y no puede ejecutar varias tareas a la vez.

    System Ninja 3.0.4 should have corrected this issue. 3.0.5 will include further improvements.

    Hi. I too have issues with freezing at exactly 91% of scanning. Well described above, tried all methods but no joy at all. Was working fine till the latest update.

    Hi Philip,

    Between 91% and 92% System Ninja will clean the Windows Temps directory (C:\Users\\AppData\Local\Temp and C:\Windows\Temp) and the .db files in the thumbnail cache directory (C:\Users\\AppData\Local\Microsoft\Windows\Explorer\*.db).

    It’s possible that a corrupt file is causing problems while scanning this area. It could also be a huge number of files in one of those directories are choking System Ninja as it tries to scan.

    I would suggest manually navigating to these directories and cleaning out the files.

    The most likely offender is the thumbnail caches, so it may be worth unchecking the ‘Thumbnail Caches’ option and seeing if that fixes it. Please confirm if this does indeed resolve the problem so we can investigate possible fixes.

    Hi, thanks for replying. Yes, it does seem to work when the thumbnail cache option is unticked. Have run it a couple of times and it hasn’t frozen, which seems promising. I like to run a smooth PC and use CCleaner a lot to get rid of junk. And Ninja used to run hitch free ever since installation.
