Dodawanie niestandardowych miniatur i tekstu możliwego do zindeksowania

Aby ułatwić znajdowanie plików powiązanych ze skrótami innych firm, możesz podczas wstawiania lub modyfikowania metadanych plików przesyłać zarówno miniatury obrazów, jak i tekst do indeksowania. Więcej informacji znajdziesz w artykule Zarządzanie metadanymi plików.
