Olá tentei procurar algo semelhante mais não achei com relação a salvar arquivo e tendo o acesso na pasta

Estou tendo o seguinte erro: 
22/02/2013 10:58:58 view.AcaoView btnLogActionPerformed
GRAVE: null
java.io.FileNotFoundException: C:\arquivo.rar (Access is denied)
O trecho do codigo é o seguinte 
//Salvar o arquivo de log no computador
        FileOutputStream outPut = null;  
        try {
            outPut = new FileOutputStream("C://arquivo.rar");
        } catch (FileNotFoundException ex) {
            Logger.getLogger(AcaoView.class.getName()).log(Level.SEVERE, null, ex);
        }
        try {  
            outPut.write(aco.getLog());
        } catch (IOException ex) {
            Logger.getLogger(AcaoView.class.getName()).log(Level.SEVERE, null, ex);
        }
Aonde o aco.getLog() é: 
public byte[] getLog() {
        return log;
    }

Tenho acesso a pasta para salvar,mais não entendo o que está sendo feito errado,estou até tentando gravar no C: para ter certeza que não é erro com qualquer tipo de permissão

Você diz no caso se meu .jar possui permisão de adminsitrator?
Como verifico e configuro,sabe me dizer?

Se estiver usando Windows Vista, 7 ou 8, provavelmente não será trivial você rodar seu programa de modo que consiga criar um arquivo diretamente em c:\ - mas você pode criar um sob c:\users\seu_usuario , por exemplo.

Mas para você rodar seu programa com permissões elevadas, de forma que você consiga realmente escrever um arquivo diretamente em c:\ (em vez de algum subdiretório ao qual você tem acesso), você precisa criar um Command Prompt como Administrador:

Start -> All Programs -> Accessories -> Command Prompt (clicar com o botão direito) -> Run as Administrator

Isso irá criar um Command Prompt a partir do qual você pode rodar seu programa Java de forma que você possa criar um arquivo em qualquer diretório.

No Windows 7 em português, se você for suficientemente esperto, pode fazer a mesma coisa (eu não sei quais são as traduções oficiais porque não tenho aqui um Windows 7 em português para eu ver aqui).
