![]() (Automatic cross-device syncing and a single set of age- and number-capped versioned backups are your friends!) FREE OUTLOOK 2010 TASK DEDUPLICATOR FREEAs for Ashisoft, I *think* they lost me when they turned the free version into a highly crippled crippleware version.Īnyway, my “curation” work is mostly done (to the point of “good enough”), and in the future I’m going to try to be *much* more disciplined about avoiding duplicates and multiple versions of the same file in different places, because eliminating duplicate and out-of-date files can be tedious, painstaking, time-consuming work, even with a good duplicate file finder. FREE OUTLOOK 2010 TASK DEDUPLICATOR UPDATEWith Auslogics, I *vaguely* remember being bombarded with banners, popups, and up-sells on its site (in a reasonably locked-down browser!) every time an update was available. I’d previously used Auslogics Duplicate File Finder and Ashisoft Duplicate File Finder - both pretty straightforward, given that I was able to use them without “reading the manual” - but both ended up alienating me. AllDup is the most sophisticated duplicate file finder I’ve used, but it has a learning curve and you need to pay close attention to the options you choose. ![]() There were a good number of outright duplicates and of superseded versions of the same file, and I used AllDup to winnow those out and end up with a single collection of unique, up-to-date files. I had different collections of data going back 20 years, on drives from dead computers and on an assortment of external drives. There are other methods (both command-line and GUI) that allow you to manage System Restore Points and Shadow Copies in a more granular fashion, but I don’t use them, so I’ll leave it to other commenters to mention them.Īs for the main focus of the article, I recently completed a *massive* amount of data-file “curation” in anticipation of setting up an NAS. Your situation and calculus may be different. And my previous Disk Cleanup was only a couple of week ago! So as I said: *significant*.ĬAVEAT: I maintain a relatively recent, “known good” clone of my system drive, and I generate versioned backups of select categories of files using FreeFileSync/RealTimeSync, so I don’t really *need* Shadow Copies or multiple Restore Points. In fact, I did it just now to refresh my recollection of details for this comment, freeing up *33GB of space*. Windows’ built-in “Disk Cleanup” tool (in Win7, at least) gives you the option (in the “Other Options” tab) of deleting all but the most recent Restore Point, and it’s something I do before periodically cloning my system drive. I just wanted to emphasize that unnecessary System Restore Points and Shadow Copies can take up a *significant* amount of drive space (though you *can* control *how much* space they do in your computer’s System properties). It’s the best I have found up to now in the free category (it also has a Pro, paid-for version). Programs vary widely in the help they bring to that operation.įrom what I see here, I will stick to Duplicate Cleaner Free. It’s very easy to delete useful files by mistake at this point. One of the more difficult steps is examining the results, and deciding what to do with them. What does this one do ? Does it force you to use this “fast hash” method ? Can you opt out of it ? It does not claim to find all duplicates, anyway.ĭeduplication is more complex than it seems. ![]() Other (good) deduplication programs offer you a choice : either search on the basis of file names, and possibly other data such as creation date, or search on the basis of contents (and then, possibly choose your hash method). Most other duplicate finders omit this step, but it really speeds things up.” This is very quick for large files, and it eliminates the vast majority of potential duplicates, as most files will have different samples. The fasthash uses small samples of the file (16 kilobytes), taken from the beginning, end, and three places in the middle then does a duplicate check based on the hash of the samples. “The app also makes use of a speed improvement I haven’t seen anywhere else: It makes an extra pass of the file list to create a ‘fasthash’. It opens the way to many false positives and false negatives. As an example: a file with a name containing “copy of”, or “.1.txt” would be considered less descriptive than one without and a file named “lkePic.jpg” is considered less descriptive than “Lake Pictures.jpg”.” The app tries to select the shortest, most descriptive name as the one to keep. ![]() “What sets this one apart is that it will make guesses about which files you want to keep based on the filename. ![]()
