    Hi all,

    I will elaborate more in an article related to email security, but for now:

    Checking file type can be tricky in Windows, especially based on the extension. Linux users have the excellent "file" command, which allows them to do this.

    Now, Windows users can also enjoy this great command.

    file for Windows:

    http://gnuwin32.sourceforge.net/packages/file.htm

    Allows you to check the REAL file type, based on a variety of criteria, including the magic number.

    See example.

    Enjoy.

    Also check out TrID, which seems much more sophisticated than this program. TrID is free and has thousands of definitions. Thre are some 3rd-party Windows frontends for TrID also.

    Found one after many many months of searching that seems to put the exclamation point on finding CORRECT files/extensions that were either changed or different.

    Try this puppy out. The benefit is you can install it then pull the folder out to place on your pen drive and it still works to a Tee! Then just Uninstall the app if you don't need or want it installed for your own reasons.

    Name is File Type Verificator

    (FREEWARE!)

    From author's website, ready to D/L.

    Test it by changing any of your normal file extensions and watch it find the proper extension. I been looking for something like this a long time for my local forensic studies without command line crap i detest. Has a very nice GUI and other options for a user's convenience.

    Hope someone finds it useful.

    I tried this one several months ago, at the same time I tested TrID. I seem to recall that FileType Verificator was noticeably slower. I ended up keeping just TrID.

    Thank you to Mrkvonic and EASTER for the posts :).

    I also noticed that FileType Verificator also uses TriD to help in it's interpretations of file types. They probably modified it for GUI purposes.

    What are you guys trying to do verify the intergrity of a file?

    -----> MD5sums it's all you need! :)

    BOTH.

    The integrity of a good file WITHOUT FORCED EXTENSION CHANGE can be compromised and detected thru MD5 of course, another alternative also is to verify by detecting/confirming a file name change, that's all.
