The name XVI32 is derived from XVI, the roman notation for the number 16.

XVI32 is one of the most popular free hex editors running under Windows.

XVI32 comes with a complete online help and requires only 975 KB 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.

Here are some key features of "XVI32":

· data inspector to view decoded numbers
· 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)
· Font and font size adjustable
· Overwrite or insert characters
· Insert text or hex string n times
· Switch byte offset (address) of first byte between 0 or 1 to examine also record structure of plain text files
· Search text or hex string, e.g. find "this text" or find "0D 0A"
· Simplified search for Unicode Latin (UTF-16) strings
· Search optionally with joker (wildcard) char that will match any character, e.g. find "A.C" or "00 2E 2E 00" where "." = "2E" (user-defined) stands for any character
· 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"
· Extremely fast "replace all" mode (if needed, additional memory is allocated beforehead, not at every single replacing operation)
· Auto-fill feature to copy bytes from current address into input field for hex string using right arrow key
· Character conversion using self-defined character table
· Easy converting of text to hex string in dialogs (e.g. "abc" -> "61 62 63")
· Decoding and encoding of 1, 2, 4, and 8 byte integers or 4/8 byte floats in 2 possible byte orders
