Chipmunk: byte-by-byte comparison of duplicate files

updated 11:50 am EDT, Thu March 20, 2008

Chipmunk file comparison

German developer Ruotger Skupin today unveiled Chipmunk 1.0, an application designed to find, compare, and delete exact duplicate files. The application performs a byte-by-byte comparison of the suspected duplicates to verify whether it is a true duplicate. Skupin claims that Chipmunk is quickly able to process hundreds of megabytes worth of information quickly. Chipmunk is currently available at an Easter discount of $20, and is normally $25.

"Chipmunk reduces the task of finding and removing duplicate files to a few mouse clicks," said Skupin. "I think Chipmunk gives the Mac user finally control over those gigabytes of old data he never dared to delete."

    bwah?

    Too bad they used a squirrel instead of a chipmunk for their icon. Oddly enough, that's the web desiger's fault (of the app site), not MacNN.

    Are you sure?

    If I know my rodents, squirrels have bushy tails; chipmunks not quite so bushy. The little rodent in the picture has somewhat bushy tail, but not quite squirrel-bushy. One could argue the artist took a bit of liberty to make his chipmunk somewhat cuter and fluffier, to avoid it looking too much like a rat. He did make it brown, rather than gray, so at least the colour is a bit more chimpunky than squirrely.

    As for the application itself, it could be extremely useful. If only it would also parse those iPhoto and iTunes xml files and do the necessary for all the duplicate files it finds...

    I know chipmunks

    I have four cats, and they don't like chipmunks, so I see lots of dead versions, all with little tails. They are tan, with a black and white racing stripe (really)!

    They are also much smaller than the squirrel.

    gave it a whirl

    Pretty effective and simple... I like it. Not exactly fast the first time you use it on a drive (it keeps a log for future reference). It shows files that have duplicates and where they are, allowing you to delete them by name (and/or hiearchy), or to simply select a volume and choose to delete files outside or inside that volume. Nothing is done automatically, which I like.

    One nice touch is that it shows them according to size, so you can focus on the files that are taking up the most space and forget the trivial ones.

    If you're a teacher that deals with digital files, this is an easy way to look for duplicates from your students when the files are handed in. It ignores the titles and metadata, so it will also expose any student trying to pass off another's work as their own.

    Could use a bit more instruction on its use... hopefully that will come.

    interface good; instructions still needed

    I'm probably pushing it too hard with several terabytes of old files I need to sort out some day (some of my files go back to CP/M-86 days). It chokes (could be that's SnowLeopard or the MacMini with only 3GB of RAM available, too, not sure). When I disconnect most of my drives and let Chipmunk review one external drive time it seems to get through the process. The email contact in the current version doesn't work, but the author is reachable and still working on the product (I went through the third party that handles non-Apple sales to reach him with some error reports).
