Analyzing Data

In addition to editing data, Cygnus provides features for analyzing data. Of course, you can view data in the edit window to see what a particular file contains. You can also send any or all of a file to your printer. But Cygnus offers more specialized means of analyzing data as well.


The Compare Files Dialog Box

The File Compare command will intelligently compare two files. The comparison is intelligent because Cygnus is able to resynchronize matching data after a difference has been found. Comparing files of different lengths is no problem at all.


(Note: The algorithm employed by the File Compare command was designed for and is much more efficient at comparing similar files. Comparing files that are nearly identical is very fast. Comparing large files that have very few matches consumes a lot of memory and is not very efficient.)


The Checksum Dialog Box

The Checksum command can be used to compute the checksum of a range of data. Cygnus comes with several checksum algorithms ready to use. Developers can add support for additional checksum algorithms by writing Cygnus extensions.




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.
