I've tried a few find duplicate programs over the years. I've never really found one I liked much. Typically, they are too simple or too difficultawkward to use, even for experienced users. Not to mention that it's always scary to let a new and unknown piece of software identify and delete important data.
AllDup is not perfect - the interface is too crowded and a bit confusing at first. Way too many buttons. But I really needed a good duplicate finder and decided to spend a few minutes to figure everything out. Once I got the hang of it, it's a very powerful and useful tool. I've identified and cleaned up many gigabytes of duplicate files. Is it the best duplicate finder out there? I have no idea, but it works and does everything I need it to do.
It didn't find all my duplicates. I can sympathize with someone trying to write software like this as it must be pretty elaborate and somewhat trying to test, still, I wish that it caught all my duplicates.
This is an update to my original review.
In that review I gave this program only 2 start because it was not doing things it should which could have caused a problem. After testing several other programs to do this job for me I have to admit even with the bugs, this program is still better than all of the others I tested. The issues about not giving a warning when deleting all files from the same group (noted in my original post) resolved it self the next day, not sure why but hey after the date changed that issue was gone. I am going to raise my score on this program to 3 stars because there are still some odd issues such as when a lot of files are in the list of dupes sometimes clicking on the group with the preview on does not show the images of the items in the group. Moving down the list to the first file in the group and making that image show then going back up to the group main list will cause all files to appear in the preview.
All that said, I will send in my findings of things that need corrected and if these things happen I would consider the paid version and bumping up the rating to 4 stars. I won't give it 5 stars unless the interface gets less cumbersome, it is a little odd to use.
Super fast and easy to use.
This dup search software has near every setting you can think of and then some.
It may be a bit extreme for some users with all the settings so I gave it a 4 star for this reason, not a 5, interface could have better grouping.
That said, it would be better to ask what this dup search CAN'T do? It will find files byte by byte, by name, by size, etc... and believe me, far too many options for me to list here. It was dead on at finding my .MP3 dup files, even those with changed name, extension, etc... but you have to set the search options correctly. This is not a basic dup finder, so if you use it, be prepared for all sorts of options. It will look at and break down to the smallest files of any folder or application which would be overboard so I set it to match by less criteria.
I've only scratched the surface of using this. There are options for scanning zip or rar, you can exclude numerous file types, include many file types, basically, you can "after getting used to the interface" fine tune your search to what you want. I think with some interface work, this will be one of the best dup finders out there.
Intense options yes, but get used to it, you have one fine application.
Works very well for finding exact duplicate files,
but the selection of folders for searches is
cumbersome, as is file type filter. This program
appears to be unable to identify duplicate songs
(song, artist, album) if the file names or file type
