Need to check a file at a given path

#include <windows.h>
#include <iostream>

using namespace std;

bool exists(char* filePath)
{
	//This will get the file attributes bitlist of the file
	DWORD fileAtt = GetFileAttributesA(filePath);

	//If an error occurred it will equal to INVALID_FILE_ATTRIBUTES
	if(fileAtt == INVALID_FILE_ATTRIBUTES)
		//So lets throw an exception when an error has occurred
		throw GetLastError();

	//If the path referers to a directory it should also not exists.
	return ( ( fileAtt & FILE_ATTRIBUTE_DIRECTORY ) == 0 ); 
}

int main()
{
	if (exists("test.txt"))
		cout << "test.txt exists!\n";
	else
		cout << "test.txt does not exists!\n";

	return 0;
}</iostream></windows.h>
