Please note, that the directory structure of NDA is not the same as the one in the host computer. Frames Fields can be stored directly in directories or within frames. At the directory level they can be referred to as any other entries, but at the frame level fields can only be referred to through the frames. The same field name can be used in several frames residing within the same directory. Otherwise, names within each subdirectory or each single frame must be unambiguos.
Names are case sensitive.
