Combine big files
<p>I'm trying to join two big files (like the UNIX cat command: cat file1 file2 > final) in C++.</p>

<p>I don't know how to do it because every method that I try it's very slow (for example, copy the second file into the first one line by line)</p>

<p>¿What is the best method for do that?</p>

<p>Sorry for being so brief, my english is not too good</p>
