Hi Stephen,
Thanks for the quick reply, it is a binary file, coming from Quicktime's mov, I need to search backward for a string 'free', then change it to 'moov', so search should start from the end of file, any ideas? Thanks,
Angelo

32 or 64 bit? What is the encoding (ASCII, UTF-8, UTF-16, etc)? Are
the updates in place (that is, overwriting existing characters) or is
it more of an inserting new characters operation?
