In case of error, how I can call function getFileName again?

Don't do `path ~ "\\" ~ filename`. Instead, use 
"std.path.buildPath". It's more portable, faster, and convenient.

Also, you should store the result in a named variable, or you'll 
reallocate a new string everytime.

 	else
 	{
 		writeln("File do not exists. Please try again");
 		getFilename(); //I need something similar, to call function 
 again.
 	}
 	
 }

Any kind of looping control structure would work. I'd advocate 
the while(1) loop with a break or return:

while(1)
{
   string filename = chomp(readln());
   string path = getcwd();
   string fullPath = buildPath(path, filename);
   if (exists(fullPath))
     return fullPath;
   writeln("File does not exists. Please try again");
}

You mistyped the function name, it's getFileName (capital N), and
you forgot "return". So:

return getFileName();
