Batu69 Posted October 31, 2016 Share Posted October 31, 2016 AllDup 4.0 has been released; the popular duplicate file finder for the Microsoft Windows operating system ships with search, interface, and customization improvements. You may download the new version of the program as a portable version that you can run from any location after download and extraction, or as an installer if you prefer it that way. The program opens with an interface that has been redesigned. Especially the iconography is different and may be easier to understand for first time users. The program displays two rows of icons on start. The first lets you start searches or look at search results, switch between profiles, open the options, or logs. The second defines the search parameters. There you find options to select one or multiple folders for the search, define search methods and options, filters, and enable or disable file previews. AllDup 4.0 The sheer number of options, toggles and switches can be intimidating at first. While advanced users may find AllDup to be the holy grail of duplicate file finders, inexperienced users should not give up on the program either. While you may configure the search and filter options in detail, it is not necessary to run searches. You can get your first search underway in a matter of seconds. All you have to do is select a folder that you want searched, and hit the start search button afterwards. That search is limited to file name comparisons though which is not the best way to find duplicates as different names or files with identical sizes may not be included in the results. Search method lets you define comparison criteria in detail. You can select one or multiple options there, for instance to search by file content and size, or by similar pictures. The performance of file content searches using hashes has improved by about 50% according to the developer, and similar pictures is a new file comparison option that finds identical and "almost identical" pictures. The latter can be useful to find duplicate pictures that use different file extensions, or have slightly different resolutions. Other new options include ignoring ID3 tags of mp3 files and metadata of FLAC files, and new file name comparison options to only compare the characters at the beginning of files, or requiring a set percentage for partial file name matches. The program displays a log window will the search runs which keeps you updated on the progress. A truckload of new options have been added to the search results window. Some allow you to display or hide information, e.g. displayed toolbars, or new search options. AllDup 4.0 supports two new command line parameters. The parameter -c runs a file content comparison search from the command line for instance. As far as negatives are concerned, there are two but they may not matter to most users. First, Windows 2000 is no longer supported by the program. Second, all profiles, program settings or stored search results from version 3 cannot be carried over to the new version. Closing Word AllDup is a powerful duplicate file finder with an impressive set of features and options. The new AllDup 4.0 version improves the program further in many regards without taking away functionality or introducing an awkward interface that is harder to use or navigate.

luisam Posted October 31, 2016 Share Posted October 31, 2016 Is really the presence of "duplicate files" a real issue? I've scanned at some moment my computer for duplicate files and certainly found a couple of dll with same filename and even same date, but really not so much as to justify a better mousetrap to get them. Ultimately, I'm not sure if I can remove a dll from some installation folder just because there is a similar one in another pack or in system32. Most common duplicated files are the audio files but I'm not sure the extent this app might detect same tune with slightly different filename at different bitrate and different metadata. And, of course I never would delete a duplicated audio without listening both, even if one of them has apparently a better bitrate. Sometimes the real quality of a 128 kbps files is actually better then another at 320 kbps! There are lots of fake bitrates, by people who knowing or not, redigitize low bitrate rips from Youtube or another source to FLAC or burn a CD with low bitrat files and than upload the image. Or even, simply, the original record was a high bitrate copy of a bad quality take. Also, I've encountered duplicate ebooks: same title in pdf, epub, mobi, lit and even txt. Which one would you keep, deleting the rest? No way to know without checking. Believe it or not, sometimes the best option is txt! Go for optimized size? The better might be biggest one in PDF, a very good scanned copy, reading it you might feel like reading the original printed copy.! So, excuse me, I don't trust duplicate file finders.

Pete 12 Posted October 31, 2016 Share Posted October 31, 2016 You are right , take care with these tools, you simply can not remove some duplicats without crippling your rig.......... Link to comment Share on other sites More sharing options...
Pequi Posted October 31, 2016 Share Posted October 31, 2016 I often download an app from several sources, then run a dupchecker to see if any have been doctored, so as a security measure, they are valid. As to MP3's, I agree with Luisam, too many 96 kbps ripped from Youtube and re-encoded to 320 kbps, as people tend to download the higher "quality" files it makes them more popular. Just dropping them into Spec http://spek.cc/ Is far more useful than using a dup-detector. You can detect the real bitrates in an instant. Link to comment Share on other sites More sharing options...
