Need to create binary files with data for Your program, game etc.? Tired of using hex-editor and editing the file manually with the risk of structure-mismatches? Too lazy to reedit complete file after changing structure members order or size? "data2bin" is a utility that takes: 1. Your structures description (you can use integers of different sizes and endiannesses, null-terminated text strings, fixed-size binary strings, structures, arrays...) 2. Your data in a XML file written down according to defined structure. ... and produces final binary file. It is able to pad Your strings with defined padding, check Your integers' sizes, it can fill default values where You didn't supply data, it can also, for example, put a "blank" array member at the end of an array etc. Whenever You change your structure in Your code, just update the data-description file and "rebuild" Your binary files without touching XML data files!

BinCoMerge is a binary files diff at byte resolution. It shows hexadecimal and raw ASCII data. BinCoMerge is seeking for common blocks from the bigger ones to the lower ones. It works by levels of minimum block sizes which are powers of 2. For example, with a file sizing between 16 KiB and 32 KiB, Bincomerge will firstly seek for all common blocks bigger than 16 KiB. Then, it will seek for all common bigger than 8 KiB, then 4KiB, 2KiB, 1024 Bytes... Because it works by levels, BinCoMerge can show some results before it finishes.

A small program that reads and change bytes in files.

Klang is a project that allows viewing and editing of binary files in a structured way. Unlike traditional hex editors, Klang provides a hierarchical view of many binary file types that can be 'chunked', such as WAV and AIFF.

Let's say you've gathered a bunch of lists from across the internet, in various formats and from various sources. Let's say you've cat'ed them together into one giant master list, sorted and unique'd. However, after starting to work with the master list, you realize it is riddled with a bunch of NULL bytes, which chokes your list processor. removeNULLbytes was made to solve this problem. It will read a master list line by line, remove any NULL bytes, and then write the result into a second file. It treats all files as binary. This is a simple python script. So simple in fact, that anybody with half an inkling can string together a working approximation with a few minutes on stackoverflow.com. However, if you're as lazy as I am, you'll look for a script already written to do the job for you. This is that script.
