Adding comments to a file in windows explorer.

    I have Win7 SP1. How do I add comments to any file in Windows
    Explorer. I recall that in Windows XP one could type in any desired
    remark and this would then be attached to the file and this could then
    be displayed in the Explorer right window.

    I can do this for image files, but not for mpg files.

    In Win 7 when I get to the "Properties" and go to the "Details" tab,
    all the details are locked and there is no way to enter details in the
    "comments" dialogue. Is there some way around this, and how much
    text can I enter in the 'comments' property. Is there a "memo" like
    in Access?

    Try 'Custom', instead of 'Details'.

    Under Vista and Windows 7, Microsoft controls your computer even if you
    are the administrator. Welcome to the club. Who says change is good? :-(

    Maybe you should be using an image editing programme.

    There's no 'custom' anywhere in the properties.

    No, it works OK for images. Indeed the 'comments' field here can
    contain a great deal of text. But I can't do it for mpg movies. Why
    wont it work for movies when it works for images?

    Some types of file contain a metadata header, others don't, windows
    knows how to display and edit metadata from some file, not others.

    e.g. you can probably do it it .jpg images, but not to .png images,

    windows can't just go poking comments into a .mpg file, without knowing
    it won't corrupt the file.

    Well, you are right, it does NOT show 'custom' for any media file ????

    Opening the file in Media Player does not allow to change anything either.

    IIRC, only tiff and jpg use exif data.

    Are you sure about that? I'm not aware of that capability. Some third-
    party utilities can save comments in text files that are associated
    with files, but I don't think Windows has any similar built-in feature.

    > I can do this for image files, but not for mpg files.


    OK, I guess it could be done for image files, since they can contain
    EXIF and ITPC information tags, but not files in general, as you state.

    In other words, the metadata is *in* the file, not residing outside
    floating independently somehwere in the file system. Windows Explorer
    can show the metadata for some files but can't edit every filetype's
    metadata. That's when you use a 3rd party editor of that filetype to
    modify the metadata to values you want.

    Windows knows about EXIF data; see http://en.wikipedia.org/wiki/Exif
    (see the "Viewing and editing Exif data" section and see the comments
    regarding Windows XP). That's only one type of metadata in various file
    types.

    Not all media files have metadata or it's not very complete; i.e., they
    may carry technical metadata (e.g., resolution, duration) but lack
    bibliographic metadata. From what I've read, some media files cannot
    simply have their metadata edited but instead have to be reencoded with
    the new metadata values (i.e., you rebuild the file with the new
    metadata). MPEG-7 is supposed to add more metadata.

    For a list of which media file types contain metadata, how much or what
    type, read the wiki article at:

    http://en.wikipedia.org/wiki/Comparison_of_container_formats

    You can do it with Alternate Data Streams. It's a bit of a rigmarole,
    but it can be done. I just added some sample text to a *.mp3 file using
    the method shown here under "Creating an AltDS":
    http://www.irongeek.com/i.php?page=security/altds

    The security implications of AltDS are, to say the least, interesting...

    One, that requires that you use NTFS as your file system on whatever
    hard disk where you store the file(s). Two, you won't be able to
    transfer that NTFS data to other hosts when you copy the files because
    those ADS for files in one NTFS won't transfer to create an ADS in the
    other NTFS file system. Three, most removable media you use to
    physically transfer or archive those files (CD/DVD, flash drives) don't
    use NTFS so copying the files there will lose the ADS metadata provided
    by using NTFS. It is a local-only solution with the caveat that you
    copy/move the files with ADS to somewhere within that same file system
    in that instance of Windows.

    ADS has been around 1992 since NT3.1 ever since NTFS was introduced but
    Microsoft has never provided any bundled tools in Windows to let users
    easily see and modify them. However, there have long been ADS tools
    available and most anti-virus programs began scanning ADS since around
    2002, if not earlier.

    http://en.wikipedia.org/wiki/NTFS#Alternate_data_streams_.28ADS.29

    You could have a .txt file that was normally only 5KB in size (number of
    bytes for the file, not how much disk space it consumed) but have an ADS
    that was 100MB in size that carried a video or malicious code. One
    malware used ADS to consume users' hard disks by attaching large ADS to
    files. The user couldn't see where all their disk space was getting
    consumed. As for malicious code, yeah, it's sitting there in an ADS
    (and AV programs scan there) but some parent process had to first load
    that then read the ADS so the AV really needed to target identifying the
    parent malware. Malicious code can reside in an ADS but something else
    has to load and pass control to it.

    Having the user append an ADS to their media file means its content
    won't be in any standard format that anyone else can read. Even the OP
    will have problems with this scheme if not thoroughly planned out since
    later the OP may not know what the data means in that ADS that he has to
    manually extract from the file.

    What properties are available and whether or not you can change them
    varies from file type to file type, even variations of the same general
    type of file. For example, you can add or change a comment for a JPG
    image file but not for a PNG image file.

    For detailed information on how to change property values for a file,
    open Start>Help and Support and search for "File properties." Select
    item 1 from the results, "Change the properties for a file."

    Many files, such as images, media files, Office files, have places in
    the file format to store this kind of information. For other files,
    WinXP used NTFS alternate streams to store these things. But MS
    dropped that when they brought out Vista.

    I doubt that many users of Win7 are using FAT32.

    Are you saying that it is not possible to copy a file containing an ADS
    to an external NTFS-formatted drive and retain the ADS? I haven't been
    able to find that info - have you a ref for it? If true, what would be
    the point of "infecting" a file via ADS with *.exe malware if it
    couldn't be copied from, eg, an internet server to a home computer?

    The OP just wanted some way to store information with his mpg files.
    ADS can do that.

    I agree with you. I guess the best way to get round the problem is to
    copy the file to a FAT32 disk, which would strip off any ADS from the
    file, then copy the file back to your NTFS disk.

    Not sure what you mean by this. I would assume that the OP would name
    the ADS file in the same way any normal file would be named. Even if
    the ADS file name had been forgotten, use of something like LADS would
    reveal it.

    I guess I *was* born yesterday!

    That was (1) new to me, and (2) possibly even useful.

    Muchas Thanks.

    What file system does the CD/DVD media use?
    What file system does the USB thumb/flash drive typically use?
    If you use online storage, how did you transport the file to there?

    I badly stated what I meant to say. Forks in a file system (aka ADS for
    NTFS) often don't survive transport of the forked file. You have to be
    careful regarding transport of the file between file systems and hosts
    to ensure survival of the forked content (the alternate data stream).
    Transport to a file system that doesn't support forked files results in
    stripping or separation of the forked content. Zipping the file into an
    ..zip archive file will strip out the forked content. I haven't tested
    FTP but suspect that will strip the forked content as the '[m]get'
    command probably only gets the primary stream.

    The malware or its installer, when ran, can hide some of its code in an
    ADS. If your security software doesn't scan the ADS of files, it may
    miss its signature for the code stored there. However, that also means
    the security software missed the parent process that executed to then
    store some code in an ADS. It's not just malicious code that gets
    hidden in an ADS. In the past, there have been trojans whose function
    was to disable your computer buy consuming all its disk space which it
    did by appending huge randomly generated bytes in the ADS onto many
    files. Even if you deleted the malware, its effect remained in place
    with all the disk consumption for the ADS. I don't know how much
    malware utilitizes the ADS and if they mostly use it to store code
    (which still requires a parent process to load which means being
    susceptible to detection by security software now or later) or if they
    mostly use it to bloat file sizes that are invisible to the user with
    the normal tools provided in Windows to consume the disk. I've seen
    only a couple cases where code was stored in the ADS but seen more of
    the bloated file cases.

    I've also seen an anti-virus program (Kaspersky) that uses the ADS.
    They would scan a file and then save some hash value (checksum) in the
    ADS. On subsequent AV scans, the ADS content was used to determined if
    the file had been modified and, if not, would skip that file since it
    hasn't changed and has already been scanned. This was their "smart"
    scan that would bypass previously scanned files.

    http://www.kaspersky.com/news?id=177718126
    "Kaspersky Anti-Virus products use NTFS Alternate Data Streams to hold
    checksum data about files on the user's system: if a checksum remains
    unchanged from one scan to another, Kaspersky Lab's products know the
    file has not been tampered with and do not, therefore, require a repeat
    scan."

    That article was dated 6 years ago so I don't know if Kaspersky is still
    using ADS to store its checksums to short-circuit later scans.

    Yes, ADS is "some way". It's not a good stable way except within the
    same file system on a host. Files that carry along their own metadata
    do that for a reason: the metadata remains intact *in* the file no
    matter where the file gets copied.

    After over a decade of availability of NTFS with its ADS feature (to
    support forked file content), Microsoft still fails to provide an easy
    means for users to see if there is an alternate data stream on a file
    and what it contains. Windows Explorer has yet to even indicate there
    is a non-empty ADS attached to a file.

    But if you know about ADS (which is required for you to doing the
    "strip" by copying between different file systems) then you also know
    there are 3rd party tools to manage the ADS. Rather than produce a 2nd
    generation copy of a file to get rid of its ADS, use a tool to just
    strip the ADS without touching the primary stream.

    The OP would have to design some template for the data he stores in the
    ADS for all his media files. Then there be a uniform layout to that
    data so it is recognizable every time he looks at the ADS for each file.
    He could make it free-format but he will have to read it himself versus
    using it to monitor or control his media files.

    Plus the OP will need to provide a means of editing the file, attaching
    it as an ADS, and then later extracting the ADS and open in the editor
    again. Yes, that can be done but it isn't a simple setup. It certainly
    won't be any information that the OP will see as a column in Windows
    Explorer or as data presented in the Properties sheet for a file (but
    then not all metadata can be presented there, anyway).

    For EXIF, there are many 3rd party viewers that can be easily used to
    view the metadata. I haven't bothered to investigate if there is an
    all-in-one metadata viewer that will show metadata for all filetypes
    (that support metadata). It also appears the OP wants to edit the
    metadata. For some filetypes, editing is easy but for some a change in
    metadata means reencoding the file. The MPG files the OP asked about
    don't have metadata in them.

    I have seen programs that provide additional info on files. They run as
    a background process. For a file, you use this other software to add
    notes or comments for the file. Then later you can review those notes.
    Alas, I've never bothered to use such file tracking software to add
    comments to them so someone else would have to comment on such software.
