Throwing a filename Exception

Prex (4)
How do I, using try, throw, catch, check to see if a file exists. Then if it doesn't it catches the exception and let's the user know. Here's what I have so far

	string filename;
	ifstream infile;
	bool loop = false, rand = true;

	while (!loop)
	{
		rand = true;
		cout << "Please input the file name" << endl;
		cin >> filename;
		filename = "c://" + filename;
		try
		{
			infile.open(filename.c_str());
			
		}
		catch(...)
		{
			cout << "File not found" << endl;
			rand = false;
		}
		if(rand)
			loop = true;

	}


I also have an exception class simply called Exception, so here's this

#ifndef H_EXCEPTION
#define H_EXCEPTION

#include <stdexcept>
#include <string>

using namespace std;

class Exception : public runtime_error
{
public:
	Exception():
		runtime_error("The file name is incorrect!")
	{	}
};


#endif
