XVI32 is a freeware hex editor running under Windows. The name XVI32 is derived from XVI, the roman notation for the number 16. XVI32 and all of its components are developed by myself (except for RxPopupMenu from RxLib which I'm using since version 1.6).

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 doesnt write any data to your registry.
XVI32 Features:
1. XVI32 is a portable application, i.e. no setup program is needed
2. Data Inspector to show permanently decoding of numbers
3. Built-in XVI32script interpreter allows to automate editing or share patches. More...
4. Computing of CRC16 (standard) and CRC32 (PKZIP compatible) checksums for complete file and selected block (only if block is currently selected)
5. Easily works with huge files. Try to open a 60 MB sized text file with some other hex editors (not to speak about Wordpad), then use XVI32...
6. XVI32 allows to edit files up to 2 GB (enough virtual memory provided, of course)
7. For your convenience, XVI32 stores settings and last used search strings etc. in XVI32.INI file
8. Progress indication in percent for most operations
9. You can abort nearly all operations (reading/writing files, search, replace, print...)
10. Display of both text (ASCII/ANSI) and hexadecimal representation
11. Two synchronous cursors in text and hex area
12. Wheel mouse support
13. Fully resizeable window (change number of rows and columns)
14. Font and font size adjustable
15. Overwrite or insert characters
16. Insert text or hex string n times
17. Switch byte offset (address) of first byte between 0 or 1 to examine also record structure of plain text files
18. Search text or hex string, e.g. find "this text" or find "0D 0A"
19. 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
20. Fast searching algorithm (Quicksearch) for both search directions (down/up)
21. Count occurences of text or hex string
22. Replace text or hex string, e.g. replace "0D 0A" by "0A" or replace "0D 0A" by text "EOL"
23. Simplified search for Unicode Latin (UTF-16) strings
24. Extremely fast "replace all" mode (if needed, additional memory is allocated beforehead, not at every single replacing operation)
25. Auto-fill feature to copy bytes from current address into input field for hex string using right arrow key
26. Character conversion using self-defined character table
27. Easy converting of text to hex string in dialogs (e.g. "abc" -> "61 62 63")
28. Decoding and encoding of 1, 2, 4, and 8 byte integers and floats in 2 possible byte orders (optionally shown permanently by Data Inspector)
29. Bit manipulation (view or set bits)
30. Open file in Read Only mode (e.g. if opened by another application or to avoid unintentional modifications)
31. Write block to file
32. Copy, move or delete block
33. Clipboard support
34. Goto address (absolute or relative up/down)
35. Bookmarks
36. Enter jump width and jump up/down (useful for files with fixed record length)
37. Patch BORLAND PASCAL 7.0 EXE files for execution on processors > 200 MHz
38. Shredder data (overwrite all bytes with binary zeroes)
39. Printing with preview or print to file
40. Easily access most recently used files
41. No setup programm needed, doesn't write any data to registry
42. And last, but not least: XVI32 is free!

XVI32 is loading the complete file into (virtual) memory. Memory is allocated dynamically, i.e. only as much memory as needed for the actual file size will be used. To achieve better performance,
