Does anyone know exactly how Version XP010 of Robocopy checks for file differences during its copy process? I've read in countless forums how "program such-and-such" would find differences in a file whereas Robocopy would not. Is Robocopy calculating some sort of CRC value from the destination file (and thus comparing that value to the source file's), or does it have another method of comparison aside from the obvious file size and time/datestamp?
