Thread: Can I not call fstream to write to two files sequentially?

I opened a stream using this very function

fstream index("c:\\windows\\desktop\\index.htm", ios:ut);

I then close it using

index.close();

I then open a new stream called multimedia

fstream multimedia("c:\\windows\\desktop\\multimedia.htm", ios:ut);

After writing to the file through the stream both times, the index stream works but multimedia does not, what could be causing this?
