Hi Paul,
Importing is a function one can use to transfer a file to another
device, for example, one braille-note to another via a null modem cable.
Export is the opposite, that is, the ability to receive a file given you by
another machine. Braille to text is the translation of a braille file into
text. I don't know what the purpose of text files, or rather, translating
them to text, might be, but that is what the options are for. Hope this
helps.Caitlin
