    Default OT: Duplicate file removal/condense folders

    I know this has nothing to do with NetObjects, but I also know that the
    people who frequent these groups are a mine of information.

    Over the years, I've built up a large repository of backup folders. (I
    backup all my NOF work/data/images folders etc monthly, so I have folders
    Aug2002 - Jan2007 plus some others) All are on a second hard drive installed
    in my pc, plus mirrored onto a USB hard drive. This is in addition to daily
    incremental backups using Acronis, which I've used for the last year.

    By the very nature of the folders being backed up, a lot of files are
    duplicated, sometimes over several months.
    Does anyone have any suggestions for a software utility (cheap or preferably
    free!) that is capable of identifying duplicate files reliably? If I was
    sure of being able to clear only duplicates - not just the oldest version of
    e.g a .nod file, then I could consolidate a lot of the spurious stuff.
    I realise there's a lot of stuff listed on Google, but would rather have an
    opinion from someone who's actually used a particular utility.

    Thanks,

    Ken

    Hi Ken,

    I can only offer the following advice:

    Having too many backups of any particular file beats the heck out of
    having too few, or (0).

    Disk space is cheap nowadays. Don't sweat having duplicate copies of
    data. The amount of disk wasted by duplicated data is truly
    insignificant compared to the risk of not having it available when (not
    if) one or more of your primary working hard drives fails and you
    discover that a sole backup copy got corrupted.

    Been there, done that, did not get the t-shirt :-).

    Hi -

    Duplicate File Detection:

    WinMerge. It's freeware & works beautifully. Not only will it compare
    files, but will compare folders & list which files are different.

    Binary & compressed files can only be compared. Text files (incl. html,
    etc.) can not only be compared, but give you a line by line comparison & you
    can copy from one to the other to make them the same.

    I work with several other developers & occasionally code gets out of synch
    (someone updates an older version 'cause they didn't check out the most
    recent) - it works like a charm.

    Many thanks, Karl and Garret.

    Karl, your way of thinking re backups mirrors mine - I forgot to mention all
    the backups are also stored on dvd. (Belt, braces and extra string ) More
    than once has a long forgotten backup saved hours of work, or an old email
    or document been resurrected to prove a particular point.
    It's just that time of year for 'spring cleaning', and apart from
    documents/work etc, I know I have many duplicates of things like NOF
    software updates, plus other purchased software with associated updates.
    Using Windows search as an example, I found 9 copies of my original NOF9
    download, plus I've already got 4 of NOF 10. And that's without the
    dvd's..................

    Garret, thanks for pointing out Winmerge. It looks more or less exactly what
    I wanted, and even though I've only played with it for about ten minutes, it
    looks easy to use. I liked the way each file is marked as duplicate or
    unique, making it fairly simple to create one 'master' backup folder.

    Thanks,

    Ken
