Do you mean replacing some bytes pattern with the same amount of bytes, without shifting the rest of the file?

yes. and which "read block size" use? 1byte is slow (file~3Mb), and in order to use bigger "read block size" i need an algorythm )

In which operating system? In Windows you could use the file mapping and thus "read block" wouldn't be necessary at all.
