Péssima ferramenta

O aplicativo não consegue identificar arquivos doc, xls ou ppt duplicados. A interface e funcionamento não são amigáveis. Totalmente lenta no funcionamento e ainda não permite a exclusão dos arquivos no próprio ambiente. O usuário é obrigado a ir no finder e fazer a exclusão dos arquivos. Não recomendaria nem para o meu pior inimigo. Foi somente dinheiro jogado fora.
