Does anyone know if it's possible to use OpenWrite[...], or related functions like BinaryWrite[...], without erasing the existing file? That is, I have a huge file that I do not want to load into memory; I just want to write over 16 bytes at a specific position in the file. It seems to me that this should be possible, but I do not find the options/commands to do so. Anyone suggestions? Am I missing something obvious here?
