Duplicate File Detective 4.0

Hunt Down Your Duplicate Files

Before you drop some valuable dollars on a larger hard drive, have you ever stopped to consider how much of your disk space is taken up by duplicate files? That's the thing about duplicate files - most times, you aren't even aware of their existence! Sometimes entire directories get duplicated when you accidentally execute a copy operation when you intended to move the files. Other times, you'll download files into different directories, or updated software versions change where their configuration files are stored, without deleting the old ones. No matter what the cause, you can be certain that Duplicate File Detective will root out all of your duplicate files quickly and easily!

Duplicate File Detective is a brilliant piece of file management software that identifies all of the duplicate files across multiple directories, drives, even network shares, and lets you move, compress, or delete them in a snap. You'll instantly experience increased system and application performance when you give your computer lots of elbow room to move! And with native 64-bit support, you never have to worry about having too many duplicate files in too many locations, because Duplicate File Detective will handle it all with ease. A sleek and intuitive interface gives you the power to customize your Duplicate File Detective experience! Dock panels wherever you like, set the program to auto-hide, or close panels entirely - it's all up to you.

Have you been burned by other duplicate file managers that deleted songs that weren't actually duplicates? Duplicate File Detective has advanced support for duplicate song detection, comparing audio tags, bit rates, duration, and so much more - virtually ensuring that if a song is marked as a duplicate, it is TRULY a duplicate. The program even has the ability to peek inside of ZIP archives to ensure that duplicate ZIP files aren't missed, even if they have different header values! Best of all, new hash value storage means even quicker duplicate detection in future sessions!

Stuart Mallion Is this a one off payment or a licence that has to be renewed every year?
May 15 2011 at 10:58pm
Mark Richards Hi Stuart,

All licenses are permanent, requiring no annual renewal.

S B Duplicate File Detective probably owns its category (at least I haven't seen anything that comes close).

I've used the wonderful LookDisk for years, but I have been watching DFD and it's now time to change. DFD has been powerful and professional since I first came across it, and it has really evolved in the years since.

DFD 's user interface is very modern and convenient, and various work settings can be packaged into "projects." You can control almost everything.

DFD seems to have all of the usual advanced search functions, and then some (name, filetype, content, directories, dates, sizes, exclusions, regular expressions, etc.) as well as direct support for managing the duplicates found (grouping, dates, sizes, most-recent, choosing, marking, tagging, removing, zipping, etc., etc.) all in a well-thought-out insightful and helpful way, and with intelligently chosen defaults.

DFD is surprisingly fast, and does take advantage of multiple cores. For us information-freaks, it can continuously display lots of descriptive data about what's going on and what it has found.

You can enable logging. It has lots of cross-referenced help--including *useful* pop-up help for things you may have missed.

This is very evolved, insightful, and powerful software, and Key Metric has now built in the technology to add new generations of even more powerful functions in future versions.

This is a special opportunity: version 4 has just been released (last month, with lots of powerful additions: native x64 support, taking advantage of media file tags, caching its hash functions--all of which can open major doors to more power) and it's half price.

It's already helping. Thanks Key Metric & BDJ. Count me in.

Mark Richards Hi S B,

Thank you for the kind words. :-)

We've been very fortunate. Duplicate File Detective has been under active development since 2004 (the first release was in early 2005) and is used "in the field" (e.g. the real world) by many thousands of customers - a good percentage of them business users that *rely* on it.

These users are the backbone of Duplicate File Detective - and they've helped us to move the product in a direction that is geared toward the professional/power user. We're very lucky to have their feedback and ideas to help guide us.

And there's still work left to do. Version 4.0 is just out the door and we're already gearing up to work on 4.1 (a free upgrade to all v4.0 license holders). Ultimately, we don't offer Duplicate File Detective on Bits du Jour for the money (we barely break even when we sell through this channel) - we do it to get more users... more feedback... even more criticism. Because that's what will help us evolve Duplicate File Detective into the future.

Tazzie @ S B ... thanks so much for the indepth review. As it happens, I have been trying to plan consolidation and organization of my folders and files, and this is coming just in the nick of time for me to give it a real work out.

@ Mark Richards ... a good software developer/enduser relationship is a two-way street ... if you've developed a good relationship with your consumers, there's a good chance it's because you demonstrated their confidence in you and encouraged their feedback and participation. This in turn encourages me, cos I like to know I can develop the same relationship with the developer of a program that may turn out to be one of my PC workhorses!

Roberto we will have foldersizes again in BDJ? :)
i played with DFD trial and looks great, really fast and dont hangs my pc when heavily searching.
May 19 2011 at 2:42am
Mark Richards Hi Roberto,

> we will have foldersizes again in BDJ?

We'll speak with the folks at Bits du Jour and see what we can arrange. :-)
Key Metric Software Vendor - May 19 2011 at 4:14am
Stuart Mallion I've been 'playing' with the trial version too, I'm so glad I put my name down for it on BdJ.
I'm impressed with the SmartMark bit, very nifty.
What I don't understand is....... how come I've not found this before?
May 19 2011 at 8:22am
P Davis Do you have a USB stick version? Sometimes you want to run it once on an independent system and not have to install and uninstall. DFD would be helpful when I am helping my mother and her friends with their computer issues.

I was not going to buy anything today but after reading SB's review and looking at additional product details on your site, I am in, especially at this price.

H. H. Hallo,
the following questions occured during testing duplicate file detective:
1. does duplicate file detective have any features the programe
dupehunter professional 9.5 does not have? The duplicate file
hunter has e.g. many opportunities to work with the result lists

2. is it possible to select all files of a specified drive or folder
(with potentially subfolders) for deleting duplicates automatically?
3. Is it possible to select all files of a specified drive or folder
(with potentially subfolders) for being portected from deleting
II didn't find these features reading the help manual, but
possibly I just didn't ecognize it because of a lack of time for
trying out)
4. may there be an option for searching for duplicate folders as well in a vuture version (like pilotman clonetools)?
That would be a really intersting feature and an additional arguent for buying duplicate file dtective
Thank you for answering
with kind regards
H.H.
