I guess the best way to know is to test it!

Put a try block to catch all and enter an invalid file. See what happens?

Re: do CopyFile() DeletFile() function throw exception?

You could use the File::Exists to first check if that file exists and then it will not through an exception.

C++ Syntax (Toggle Plain Text)
String^ FileOne = "C:\\File1.txt";
String^ FileTwo = "C:\\File2.txt";
 
if( File::Exists(FileOne) 
{
	File::Copy(FileOne, FileTwo);
}
String^ FileOne = "C:\\File1.txt";
String^ FileTwo = "C:\\File2.txt";

if( File::Exists(FileOne) 
{
	File::Copy(FileOne, FileTwo);
}

C++ Syntax (Toggle Plain Text)
String^ FileOne = "C:\\File1.txt";
String^ FileTwo = "C:\\File2.txt";
 
if( File::Exists(FileOne) 
{
	try
	{
		File::Copy(FileOne, FileTwo);
	}
	catch(Exception^ Ex )
	{
		MessageBox::Show("Something is wrong");
	}
}
String^ FileOne = "C:\\File1.txt";
String^ FileTwo = "C:\\File2.txt";

if( File::Exists(FileOne) 
{
	try
	{
		File::Copy(FileOne, FileTwo);
	}
	catch(Exception^ Ex )
	{
		MessageBox::Show("Something is wrong");
	}
}
