In a building project for example this can happen if a photo is taken of a building area, and it can be put in several places, one representing the project, another a particular material used, and although digitally the same semantically they are different and you don't want them cleaned up but kept as several. Although digitally the same photo, it's actually not, as one is an example of one plant, and the other an example of another. For example if I have a photo that has two different plants in, I will have the photo in two different folders representing the different plants.

Which leads to a scoring system according to whether size-modified or name match (or creation TS if that's used for tracking), or actually a matching strategy sequence where you have a list of strategies that are tried in turn and as items are found they are removed from the candidate pile to search in.Īll matched ones ideally should be content-checked but if they're on different devices mutually offline to each other (such as two removable drives, or a computer in a different place) after compiling the candidates MD5 can be compiled by making the devices online.Īdditional problems arise because you can have a file in two places represented different things. If creation TS isn't usable many of them can be provisionally matched on having the same name or name part (for example my photos get named to TS but some get titles added). Matching files where one has been modified is a bit more complex but if you know in advance this is going to get needed you can make the original copies preserving the creation TS and they can be matched on creation TS rather than modified TS. Issues arise with packages that preset the modified date on their installation files and happen to have the same size as then fundamentally different files will match but they're not going to be files you've made yourself if you're doing a targetted match.

A content check gives extra assurance as no one likes to delete files blindly and covers for situations where one of the files has been corrupted, since the content won't match even if the file information does.Ĭhecking the results/actions manually of a simple situation isn't so bad.Ĭommonly size-modified (using the underlying filesystem values) is an easy one to start with unless files are on or have travelled across file systems such as a memory stick or zip in which case a TS leeway has to be given. It's surprising how many there are.In my experience finding duplicate files in general is at times a non-trivial task and when in bulk best done with a program specialised for it that will do content checks. The only tricky thing to be really careful about is that none of the duplicate samples that are being trashed are referenced from a Live set (or if so they are referenced to the other file beforehand), but this really helps trimming the size down and not having to audition duplicates when selecting samples. DupeGuru is a close second to Araxis but it doesn't work well finding duplicate pics, like scanning an iPhoto library and it doesn't quite all the duplicates that the other apps did.ĭecloner has a nice interface and a handy quicklook feature to do faster comparisons but it performed the worst, missing a lot of duplicates in the results. Tidy Up has a horrible unnecessarily complicated UI for what it does though.
It has also been finding the most duplicates without any incorrect results that aren't quite a match.Īraxis and Tidy Up identified the most duplicates where the others didn't find as many when running the same search.
So far, Araxis is taking the lead because it has the most straightforward, clean logical interface, it does everything in a single window and displays the most information about the files that is relevant to audio files and is quickest to work with for more than one search. In case anyone is interested, I've found & been trying Araxis, DupeGuru, Tidy Up, Dupe Zap and Decloner. There weren't that many in the Apple App store, but I found a decent list on MacUpdate. Yeah I'm looking for something that will search anywhere on the HD, so the iTunes dupe search is nice but won't quite cut it for this.
