Duplicate file finder recommendation?

Discussion in 'alt.windows7.general' started by Percival P. Cassidy, Sep 11, 2011.

  1. I've already looked on line and tried three of the recommended duplicate
    file utilities without success:

    1. Duplicate Cleaner found a large number of duplicates but stopped
    responding when I tried to delete files.

    2. Easy Duplicate Finder found a large number of duplicates but then
    appeared to do nothing. When I tried to End Task, it reported that the
    program was waiting for input from me, but there was no sign of a prompt.

    3. Auslogics Duplicate File Finder found a large number of duplicates,
    but when I tried to delete all but one of each set it deleted only three
    files, total.

    Can anybody recommend something that they have found to work?

    Duplicate Cleaner works for me with no problems. Finds everything and
    deletes all as instructed.

    One thing I did find with it though, it does tend to go dormant for a while
    if you try to delete a lot of files to the Recycle Bin. For a while could be
    up to an hour!!! Disable this feature, so long as you are happy with not
    having the ability to recover them, and all should be OK.

    Hey, this Duplicate Cleaner rocks! I've been using an out-of-date app
    called Duplicate Detector all of these years, it hasn't been updated
    since the XP days, and it requires special XP compatibility modes to
    work in Win 7, but it is the only thing that had all of the features I
    was looking for. Now this Dupe Cleaner does even better than this.

    Duplicate Cleaner doesn't merely *seem to* quit; three times now I have
    got the official "Duplicate Cleaner has stopped responding" message; if
    I click Debug rather than Close, it quits anyway.

    The more I use this Duplicate Cleaner, the more I like it! It's
    definitely going to replace my old XP-era dupe-finder program, Duplic8.

    One of the things that's really amazing about this program is that it
    has more options than just simply deleting the duplicate files. You can
    also rename the dupe files (to something like "duplicate_*"). Or even
    more impressively, you can replace the dupes with symbolic links.
    Symbolic links are like the Windows shortcuts on steroids; unlike
    shortcuts, applications can't tell the difference between symbolic links
    and the original file, however files that are symbolic links all just
    point to one main file, so they don't take up any additional space on
    the disk. Only problem with it is that it only works with NTFS, not with
    FAT32.

    It's possible that is a hard link. The OS files in Windows 7 are hard linked
    to files in the store, in an effort to save data storage space. Some of the
    files have four pointers to the same data. The existence of hard links,
    makes it harder to figure out how much storage space your OS is using (like
    doing properties on individual folders and adding the numbers together).
    To study hard links first seen in Windows 7, I used my trusty Linux LiveCD,
    as the files have reference counts that are easier to see.

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

    The other kinds of options are mentioned in here. Too many options...

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

    If I was de-duping, and had the options of...

    1) Delete the spare copy.
    2) Use hard link.
    3) Use symbolic link.
    4) Use shortcut.

    I'd choose (1) purely for the simplicity. As it stands now, I know
    my document folders contain nothing but ordinary files, which means
    I have reasonable assurance they can be moved or maintained without
    thinking about it. I can move any folder in my document tree to
    any other folder, without having to think about it. And I can also
    use any copy utility I want, as copying ordinary files doesn't
    require any intelligence on the part of the utility.

    Yes, actually they are hard links. I tend to use "symbolic link"
    generically, and I refer to the subcategories "hard link" and "soft
    link" more specifically. I know some people tend to equate symbolic
    links with soft links.

    I can think of many good reasons to use links rather than simply
    deleting a file. I'll give a toyish example, if you got a music library
    subdivided into folders for each artist. Let's say you got one folder
    for Led Zepplin and another for AC/DC, most of the time it's not a
    problem, where you want to put your songs. But sometimes if those
    artists collaborated on a song, then you might want to have the song
    available in both directories. You can either copy the song into both
    directories and you'll have a duplicate, or you put it into one folder
    and link it to the other folder. It doesn't matter which one you put it
    into as it's really pointing to the same physical file in the same
    physical location.

    As for concerns about deleting the files, that's taken care of by the
    file system. If you have a file with 4 links, then when you delete one
    of the links, then the link count just goes down to 3, and then deleting
    another goes down to 2, and then down to 1, and when you finally reach
    0, that's the only time that the file will finally be physically deleted.

    I guess I should qualify my statement. I don't sort things into bins.
    I append terms to the file name, and rely on "search" to find things.
    Files and folders are only grouped, as a "housecleaning" thing. Once
    the main directory slows down, I throw all the PDFs in a PDF folder,
    all the images into an image folder, so that the main directory
    becomes a bit faster again.

    And that's why I don't need links. All my linkages are defined by
    means of "tags".

    The most complete duplicate finder and deleter

    The most complete duplicate finder and deleter I have found is "Duplicate Files Deleter".

    You can download it from here: http://duplicatefilesdeleter.com/

    I have found that, not only is it one of the fastest duplicate finders/deleters, but also is by far the most accurate one because of the way it's search engine uses MD5 info.

    DuplicateFilesDeleter is a simple, but effective tool to locate duplicate files in one or more selected search paths. It scans the files and compares them based on Byte for Byte Comparison, which ensures 100% accuracy. You can then choose to delete the selected duplicate or original files. The program is multi-threaded and performs scans quickly.

    • Hello Good day, I use a software called Duplicate Files Deleter, it's very easy to use and after it finds the duplicate files it lets you chose what you want to do with them (copy/delete/move). You can even check network files and you can check multiple paths in the same scan. This helps me alot. I hope you too.
