Download dictionaries for your e-reader
Here is how to install them on your e-reader:
- Connect the e-reader to your computer using a USB cable.
- Copy the .dic or .pbi file to the System > Dictionaries directory on the e-reader.
If the System file is not visible, it is possible that it will take some manipulation to make hidden files visible on the computer: display hidden files on Mac or Windows.
The dictionary will then be available among the selection of the different dictionaries.
