    Will .NET 4.5 be ok with killfile or just 4.0?

    Can the program be written without .NET?

    Thanks PMR

    It can but i bet it will be a huge undertaking. I did it in .NET because i can do multiple verifications on the assemblies. if it was just win32 then i would only be able to do authenticode verification - (I do not have a third-party verified cert) - Once I am able to write up the engine in pascal\delphi i will let you all test it but its not at the top of the list as i am a .NET developer lol

    4.5 should have 4.0 with it so i dont think it would matter

    Updated!

    Changes Version 0.3:
    Updated the shell extension file scanner to give proper information.
    Updated the shell extension to clear the file list when completed\cancelled operation.
    Added Cancel button the the shell extension scanner.
    Added application updater program to keep you current.
    Added manifest to the Shell Extension installer.
    Added program verification to only execute official code.
    Fixed application startup. Will now display valid commands if no list or file was sent to application.
    Improved command line access: Displayed info on invalid commands.
    Added SVM (Simple Verification Methods) to ensure application is authentic System Functions code.

    This is the fix for the issues that I saw and the issues brought up by Alpha here.
    Any other issues please tell me and they will get fixed!

    Ok in my testing using recuva after the file delete will return the garbage that we have written to the file not the original data so I think this is good for now as it does support both FAT and NTFS. The streams used do not remap the file unless the file has been expanded - plans are to allow expansion to destroy the original size! From what I see the filenames are the same the date is changed and the data is destroyed.

    Thanks!

    I have updated this. It should be slightly faster but maintain the security aspect. The buffer size is larger depending on your partition's format

    Changes Version 0.5:
    Updated core code to stop hang on cancel.
    Updated UI elements to use Windows 7 taskbar interfaces.
    Improved installer to install .NET 4
    Updated to give larger buffer size - uses HDD cluster size as default

    Be sure to tell me of any problems\issues you encounter .

    Thanks,
    PMR
