I just want to make new line after every '0D0A'

thanks in advance.

0D0A is a newline character. You want another newline character?

It sounds like what you have is a text file of hexadecimal like characters and not a binary file. If that is the case, you can read the entire file into a string and do a find/replace of all "0D0A" with "0D0A\n".
