  • LARGE FILES

    Can BC3 be modified or can a PC with BC3 be modified to do a comparison between two very large files (~ 20G)? I am looking for a way to verify Blu-ray disc images after writing them. I want to compare the disc image to the master image. There must be a way to create software to do this...Appreciate any input....

    The folder comparison's binary content comparison should work to compare files that large. The hex and text viewers won't be able to.

      It sounds to me like you want a simple yes/no, and don't care to have a fancy visual display of what's different. Have you tried "fc /b"? (fc comes with windows)

        Or if you're running GNU/Linux, you can use "diff --brief".

        Or you can compute the MD5 or SHA-1 hash of each file and see whether they're the same. There are free applications for doing that for both GNU/Linux and Windows.
