If you need to compare HTML, XML, or even binary files, only a proper diff utility will do. And ExamDiff Pro meets the gold standard for these types of utilities: Not only will it compare files, but its unique "fuzzy comparison" feature lets you determine just how drastic the changes have to be before the program flags them. This makes it invaluable for software developers, or anyone who needs to visually compare lots and lots of files quickly...
All in all, ExamDiff Pro is an extremely handy tool for Webmasters or Web designers, or for anyone who needs to maintain copies of files in two different places.
Andrew Brandt, PC World
By far the best comparison and merge program Iíve ever seen. You can compare folders (recursively or not) or versions of files, but what
makes ExamDiff ExamDiff Pro stand out is that you can use it right out of the box - the UI is incredibly intuitive - or you can adjust dozens (hundreds?)
of settings to meet your particular needs (do you want to consider two files different if there are changes in the amount of white space in lines?)
12 Absolutely and Insanely Essential Utilities For Programmers
Your product is one of the most useful utilities I own, and your personal
service and responsiveness sets an industry standard.
Jesse Liberty, Liberty Associates
ExamDiff Pro should appeal to all levels of developers, from those just learning HTML to seasoned pros.
What's changed? What hasn't? ExamDiff has your answer.
Bill Dubie and Dave Sciuto, The Shareware Report
The amount of time saved using ExamDiff is incalculable and the success I have had with my implementations can be credited, in part, to this wonderful tool.
Robert Dauman, Tech on Tech
Over the course of my computer upgrade, I have to admit that I relied on ExamDiff many times. It is a great program, and I would wholeheartedly recommend it for anyone who cares about maintaining and organizing any sort of data files.
Betsy Finn, Professional Photographer Magazine
We have been using this magnificent tool for several years. Almost every day it helps us to solve our daily tasks very efficient with minimal efforts. Being software developers we work with sources very intensive and this tool blows our "everyday-nightmare" out. ExamDiff is one of best comparison utilities on the market, if not THE best.
Kevin Dylan, Developer, Auslogics Software
No matter what files you want to compare, ExamDiff Pro loads them, puts them side by side and highlights the differences. Useful functionality for any web developer, from the novice that is now getting to grips with HTML to the advanced developer that wants an efficient tool.
George Norman, FindMySoft
ExamDiff is similar to a lot of other file comparison utilities like Winmerge.
But it is, BY FAR, the best I have ever used. It is easy to make changes within
the program itself and it is extremely customizable. You can highlight line
differences, byte differences, change the algorithm that is uses to do the
actual comparison, ignore tabs/spaces/white space, etc. I highly recommend it.
I use it daily when I am doing coding--whether it be vbs, VB.Net or who-knows-
what. It makes it very easy for me to compare different versions of code and
confirm that I am only making changes to the things that I want to actually
This is the best Diff-ing tool I have come across... This is a must have for data geeks, testers, and developers.
Having struggled with mainframe and Linux based diff programs, which only listed line numbers that differed, ExamDiff is a refreshing and powerful tool.
The best was the report function. Since I had to communicate all the changes back to my Italian translator, this was very important. ExamDiff created an HTML document (other formats are also available) that basically looked exactly like the comparison I saw in the application window. It had a little legend that explains what the colors mean and I was able to just send this document to my translator who was easily able to update his translation memory with these changes. Report generated by ExamDiff.

Excellent file comparator utility. The first graphical app I've
found good enough to wean me off the DOS-based character mode tool
I'd been using for years.
Sometimes you find yourself backing up files in one place and
editing them in another. Before you know it, you don't know which
one is the one you want to keep. Input the two files into ExamDiff
and you can compare them side by side.
ExamDiff offers a lot of great features...
This free version of a more capable shareware program has proven very
useful in comparing versions of the same script and highlighting the
differences so that I can bring things into line.
The freeware ExamDiff is brilliant, and works well with TortoiseCVS.
I recommend PrestoSoft's ExamDiff. The free tool (ExamDiff) is great,
and they offer a commercial version (ExamDiff Pro) that has some cool
features like intra-line diffing and directory diffing.
A great tool for Registry Compares. That's what I use it for the most.
I have to tell you that ExamDiff Pro 3.5 is the most gloriously wonderful piece of software I have ever discovered, where, for work satisfaction within the requirements of my job it is up against Microsoft SLQ Server, and even then only in respect of the relative size and complexity of the product.
To be able buy something that not only does what you could imagine you would want such a product to be able to do, but that keeps on surprising you with the way it does it, makes working for a living almost as good as not having to.
It kicks butt, love the fact it can do entire directories too, comes in
handy when one of my moron colleagues thinks they have checked in all of
their source files, then ExamDiff Pro comes to the rescue showing me what
I received a trial version of the product from a colleague of mine, and used
it on several occasions, when I saw my trial period had expired, I thought
it was too great of a product to pass up, so I decided to view the purchase
information, when I found out the cost, I was amazed, you could get twice as
much I'm sure for the product once a customer were to see how invaluable it
is, thanks for making such a great product at a very affordable price, it is
a tool that every developer should have.
Yesterday I had a need to compare two huge text files, about 125MB each.
I downloaded about 10 file-compare utilities from www.hotfiles.com, and tried
the lot. To my surprise, they all either: crashed, displayed garbage characters,
or arguably worse, stated that there were no differences between the two
files... Except for ExamDiff Pro, which was the ONLY utility of the lot able to
correctly handle the two files, displaying the differences found on the screen. So I
registered it on the spot. Plus the interface looks really professional and it
has some nice merge features and even supports directories and binary files. So
in a word, "thanks" for releasing an intelligently designed product for the
For the past several days I have been updating thousands of lines of code in
dozens of classes. This work would be impossible without a powerful file comparison tool.
I've used ExamDiff Pro for years and tried many other comparison tools in the same time.
ExamDiff Pro remains the best. This tool has saved me hours of work and insured that the
changes I make are accurate.
So, I thought I'd say thanks for helping me get my job done!
I am very impressed with this tool. It does everything I would want from a
diff tool, and then some.
The integration with Windows Explorer is something I wouldn't had thought
useful. But, I have already found several times that it saves some time
being able to get into the diff tool this way.
I just wanted to let you know that your software is really awesome! Had we
not started using Source-Offsite I never would have known about your product
and how really bad the diff utility that comes bundled with Source-Safe is.
The utility that Source-Offsite uses (WinDiff) is even worse, which prompted
us to look for alternatives. We evaluated each of the products listed in
the Source-Offsite help file under "Some third party alternatives to WinDiff
include:" and selected your product.
Maybe it's just me, but it seems rare to get great value for a reasonable
This is the best differencing program I have used and I only own two
shareware programs, yours (now) and ZTree. Not all shareware is made alike. Your
program is great!
ExamDiff Pro is, by far, the best differencing/merging program that I've ever
used, and I use it every time I need to merge in a new tree of the software
program we're developing. I found ExamDiff Pro after going through about 6 other
programs from download.com and finding them all woefully lacking for what I
needed. Kudos! Thanks for the good work!
Your commercial customers list concurs with what my instinct said back when
ExamDiff was first used, it is a well made program that does an excellent job
and certainly one does get their moneys worth. :-)
I had compared numerous diffing tools for use on the job (firmware
engineering), and none compared to ExamDiff Pro. I try not to pay for much
software, going the freeware route mostly. But your software was an exception.
Just wanted to let you know that I appreciate your efforts.
Just wanted to tell you that this program (ExamDiff Pro) is absolutely
amazing. It's does exactly what I want it to and it appears to be bug free as of
now. There's a lot of shareware that is not worth the money you pay for it, but
this is worth every cent.
The truth is I don't have a lot of use for a product like this - the functionality it provides is something I need only occasionally. However I was struck by what a sweet piece of software it is, and had to buy it anyway. Congratulations on a job well done! I am an ISD professional and well qualified to make this judgement.
I am very happy using ExamDiff Pro. I regularly have to merge modifications
done by several developers and ExamDiff Pro saves me a lot of time. It is very
flexible in use and that is why also hardly any mistakes are made during the
I really love your product. I use it every day, and I think it must have
saved me tens of hours already (I am a statistical programmer who always has
several versions of long, complicated programs on the go), in just the few
months I've been using it. Small, crisp, powerful, FANTASTIC program!
I have found ExamDiff Pro to be an excellent piece of software. For many
years I have used Delta (home.dti.net/open/delta.html), but this is a DOS
application, and I had searched at length for an equally powerful and
intelligent comparison tool, that was Windows based. ExamDiff Pro is the only
comparison tool I have found that fulfills these requirements, and I have found
it to be even better than Delta. I have recommended it to several of my
You have developed the application I have always wanted to... I'm a serious
software developer (Computer Engineer) who does a lot of contracting work...
needless to say, I have to diff a lot of source code! Your ExamDiff Pro software
has saved me dozens if not hundreds of man-hours since I purchased it a couple
of months ago.
Within TestComplete called on a command line after detecting a difference
in the content of an output test file, ExamDiff provided an easy, fast report of the
errors found in the application output test viewing a familiar screen format. No need
for the human testers to manually load up a program to inspect the results. What a time saver.
I have been using Examdiff Pro for almost two years now and I am completely
addicted to it. We recently started using CVS (Concurrent Version System) on
different platforms (Windows, Linux, Tru64 and VMS). In his book "Open
Source Development with CVS", the author Karl Fogel says: "If you've
never had this kind of convenient access to historical snapshots before, you may
be surprised at how quickly you come to depend on it". I fully agree with
him, but once you get used to a product like Examdiff Pro, the pathetic
"diff" output of CVS is really disappointing. You can imagine how
happy I was when I found out that in WinCVS, a popular Windows client for CVS, I
found the option "use external diff program" which cooperates
perfectly to Examdiff Pro. I just wanted to let you know about this (if you did
not already know it).
I want to compliment you on your program. It has been invaluable to me. I am
a Project Manager of Web Development for www.healthyroads.com and other
corporate / intranet web applications and ExamDiff Pro has helped me a lot. I
use ExamDiff to help me sync production with the development site of the
different web applications. We use Visual SourceSafe for version control (and
its difference utility), but ExamDiff is more user friendly. For me, I
like being able to compare folders and then drill down to the file differences.
VSS is good for a real quick difference check, but ExamDiff is better when I
have to compare more files and help developers track and isolate changes.
Basically, you are doing a great job!
EDP has been working extremely well for me. Thank you for creating such a
well-written tool. EDP is clearly one of the best tools out there. The
extensive options allow it to be easily customized for many different tasks.
Over the years, EDP has evolved extremely well. I hope you are proud of
This is really what I wanted for my work!!! I thought someone somewhere
should have thought about it. I can now ask for no more! I can now compare my
large text outputs till the character level! This will certainly increase my
productivity, my confidence in the production migrations I do for my company. I
can also keep track of all my different versions of source code, binaries.
Moreover I can leverage my UNIX experience, regular expressions and all, for
shutting off unwanted differences. This is really intelligent diffing! Others
will just keep guessing! And boy, these hundreds of gifted features, I'm only
happy to learn asap. Thanks a lot for such an intelligent, flexible,
sophisticated software at such an affordable price! I have bought many such
utilities online but ExamDiff beats them all by being light years ahead!! And I
tell you - by way of adding value to my work ExamDiff will do more than what MS
Word, Excel and all other such fancy stuff put together can ever do!!! For a
user like me, it is commonsense and usefulness which matter, not fancy features!
:)) I got 100 times the value for my money. I can only guess the kind of
thinking and hard work which have gone into this top class stuff. Hats off and
keep up the good work!!!

Excellent program. I am processing two 1 gig files for differences
as well as other very large files, etc... I appreciate your attention to
memory management, listbox limitations, notification messages, etc...
