I need a tool to compare 2 binaries. The files are quite large. Some freeware or trial tools I found on the Internet are not convenient to use for large files. Can you recommend me some tools?

If you want to find out only whether or not the files are identical, you can use the Windows fc command in binary mode:
fc.exe /b file1 file2For details, see the reference for fc
A few possibilities:
- VBinDiff (binary diff, designed for large files)
- WinDiff
- bsdiff
- HexCmp

Total Commander also has a binary compare option:go to: File \\Compare by content
ps. I guess some people may alredy be using this tool and may not be aware of the built-in feature.
My favorite "swiss knife" is Beyond Compare from http://www.scootersoftware.com/
I prefer to use objcopy to convert to hex, then use diff.
In Cygwin:
$cmp -bl <file1> <file2>
diffs binary offsets and values are in decimal and octal respectively.. Vladi.
