Free Hex Editor can be successfully used for: 1  editing binary file of large size (~1GB) in just seconds. 2  searching binary files for hexadecimal and RegEx data patterns. 3  replacing bytes with bin/hex/decimal/octal/float and RegExp data.  developing and modifying microcode programs for x86/x64 processors.
