Fast and Easy to Use

With our first version of Cygnus, our goal was to make the program very fast and easy to use. We feel we were successful with this goal. With version 2, our goal was to add many powerful new features while still keeping the program fast and easy to use. This version was a long time coming but, once again, we are proud to say we feel we have been successful in our goals.


Cygnus MDI Tabbed Interface

Click to enlarge


Cygnus uses a tabbed multiple document interface (MDI), which means that you can load multiple files side-by-side. This makes it incredibly easy to quickly compare and share data between different files.


Data can be copied and moved using simple drag and drop operations. Drag and drop refers to the processing of pressing the left mouse button down, moving the mouse, and then releasing the mouse button. You can use this technique to move data from one location to another. It can also be used to move data between files and even between applications (when the other application supports it).


Cygnus provides some features for protecting files that you open. Because the program allows you to work with files such as executable files, you will sometimes need to be careful not to make changes that would prevent the file from working. However, Cygnus can also be used to quickly insert and delete data as easily as with any word processor.


Cygnus with Data Inspector Window

The Data Inspector window makes it even easier to work with data. This window allows you to view and edit data using natural data types. This allows you to view and edit data in a more natural way when you know the type of data being edited. For more information about the Data Inspector window, please refer to the Modifying Data page.


Cygnus version 2 now contains more options that ever, allowing you to customize the program to your tastes. The Options dialog box offers several tabs of options. Screen shots of each tab are shown below.

Online Help Issues on Windows Vista

Cygnus Hex Editor runs great on the Vista Windows operating system. However, the portion of Windows used by this program to display online help is no longer included with Windows Vista. We are working to upgrade the help system but it will not be immediate.


In order to access help under Windows Vista with the existing software, you may download the help system used by this program from Microsoft at no charge. You will want to download Windows6.0-KB917607-x86.msu. The other version (Windows6.0-KB917607-x64.msu) is for 64-bit Windows.



Our Cygnus Hex Editor is sold as shareware. Shareware can be evaluated for free and without risk. We strongly recommend that you first download the software and install it on your computer. Take it for a test drive and see if it performs to your satisfaction. If you like the software, you can register (purchase) it. When you do, we'll send you a registration key that you enter into the program to fully activate the software. Because the software will already be on your computer, this method is fast, easy, and avoids all shipping and media charges. And because you'll have already used the program, you'll know exactly what you're buying.


Buying Cygnus

Registration for Cygnus is only $39.00 (USD). SoftCircuits offers many different payment methods. Site licenses are available.
