check out boost::filesystem.

I believe the syntax is something like this: 
1
2
3
4
5
6
7
8
9
10
11
12
13
 
#include <boost/filesystem.hpp>
#include <iostream>

namespace fs = boost::filesystem;
int main()
{
	fs::path MyPath("username.txt");
	std::cout << MyPath.leaf()      << std::endl;
	std::cout << MyPath.filename()  << std::endl;
	std::cout << MyPath.extension() << std::endl;
	std::cout << MyPath.stem()      << std::endl;
	return 0;
}
 
"username.txt"
"username.txt"
".txt"
"username"
Press any key to continue . . .
