Cygnus Hex Editor Version 2.50
Cygnus Hex Editor is a powerful file editor for Microsoft Windows.
Unlike text editors, which are designed to edit files that contain text
data, hex editors allow you to edit files that contain any type of data.
In addition to being fast and easy, Cygnus offers some very powerful
editing features. If you haven't yet tried Cygnus, now is the time to
check it out. If you have an older version of Cygnus, now is the time to

The Fastest and Easiest Hex Editor Available Anywhere!
Cygnus is fast. Very fast! Operations such as searching, or searching
and replacing are blazingly fast. And screen updates and most other
operations will be instantaneous on all but the slowest computers.
Cygnus is easy. With intelligent features such as a multiple document
interface (MDI), the ability to easily insert and delete bytes, simple
drag and drop operations, bookmarks and more, complex editing tasks can
be performed with ease. And with our new Data Inspector, editing data
values can be accomplished more naturally than ever possible before.

Our new Find and Replace dialogs make finding data easier and more
powerful than ever before. The Find dialog box divides searches into
three types: text, data types, and raw data. And the Replace dialog box
allows the same logic to specify both find and replace parameters. Want
to search for the Unicode text "Hello" and replace it with a FILETIME
value of 3/31/2005 9:25:00 am? Well, maybe not. But with Cygnus, this is
extremely simple and intuitive to do.

Of course Cygnus allows you to edit data by typing in hex or ASCII
values. But Cygnus provides powerful new ways to modify data as well.
The Data Inspector window allows you to view and edit data in a more
natural way as known data types, structures, and arrays.
The new Modify, Insert and Delete dialog boxes allow you to instantly
perform certain operations on any number of a particular data type.
The convert function will convert the selected data to another format.
Convert data using any of the existing conversion types or write your
own conversion add-in by writing a Cygnus

In addition to modifying data, sometimes you just need to know a little
more information about that data. Cygnus offers new tools for this as
Cygnus now offers intelligent file comparing. It is intelligent because
it can compare files of different lengths, and it can resynchronize
matching data after a difference has been found.
Cygnus also now offers checksum computations. Simply select the data
you want to perform the checksum on, and then select any of the
available checksum algorithms to compute that checksum. You can even add
new checksum types to Cygnus by writing a Cygnus

To get the most out of any Hex Editor, you'll want to be able to export
and import various types of data. You'll also want many options for
copying data to and from the clipboard.
Cygnus provides great flexibility in this area. For example, you can
select a range of data and then copy it to the clipboard as HTML code,
allowing you to place the data on a Web page.
In addition to the many ways that Cygnus can export and import data,
developers can even add support for new ways by writing Cygnus

Cygnus allows developers to write extensions to add additional
functionality to the program. Extensions allow you to create new
import/export, copy as/paste as, conversion, and checksum operations, in
addition to new data types.
Extensions are designed to be written in C and C++ but may be written
in any language that can create DLLs that export undecorated and
unmangled function names. Instructions on writing extensions are
included in the online help. No additional software or documentation
must be purchased from us.
