XVI32 - Freeware Hex Editor

Monday, April 21, 2014

XVI32 is a freeware hex editor running under Windows 9x/NT/2000/XP/Vista/7. The name XVI32 is derived from XVI, the roman notation for the number 16. XVI32 and all of its components are developed by myself.

The current release 2.55 is available since June 26, 2012. It comes with a complete online help and requires only 1.02 MB of hard disk space. There is no setup program needed - just unzip the downloaded archive to your hard disk! XVI32 doesn't write any data to your registry.

XVI32 is used by thousands of people all over the world. It was included in books like the Hacker's Guide. Even people at Microsoft ™ do use XVI32! If you don't believe me, look at http://support.microsoft.com/kb/835840/EN-GB/.


XVI32 has the following main features. Especially note the highlighted advantages of XVI32.
  • XVI32 is a portable application, i.e. no setup program is needed, you can run XVI32 from your USB stick, no data is written to the registry
  • data inspector to view decoded numbers (see screen shot; can be turned off).
  • Has built-in script interpreter.
  • Easily works with huge files. Try to open a 60 MB sized text file with some other hex editor (not to speak about Wordpad), then use XVI32... If you don't have such a huge text file, use my freeware tool RndFile to create one
  • XVI32 allows to edit files up to 2 GB (enough virtual memory provided, of course)
  • For your convenience, XVI32 stores settings and last used search strings etc. in XVI32.INI file
  • Progress indication in percent for most operations
  • You can abort nearly all operations (reading/writing files, search, replace, print...)
  • Display of both text (ASCII/ANSI) and hexadecimal representation
  • Two synchronous cursors in text and hex area
  • Fully resizeable window (change number of rows and columns)

  • Fast searching algorithm (Quicksearch) for both search directions (down/up)
  • Count occurences of text or hex string
  • Replace text or hex string, e.g. replace "0D 0A" by "0A" or replace "0D 0A" by text "EOL"
