Use FileBinReplace utility to search and replace data in binary files.
FileBinReplace is a command line utility that can be used to search and replace
data in binary files. FileBinReplace is very fast and can process multiple files specified
with a file mask. Because binary files usually have fixed format you should be very
careful not to damage the internal structure of these files. For example, if you specify
search and replace strings of different length the length and structure of the produced
files will also differ from the source files. As a result the produced files may not work
as expected.
