Question

The Dictionary Directories branch under Configuration - Spell Checker supports specification of directories to be used for storing information related to spell checking:

Personal data directory

The directory specified here will be used to store words added to user dictionaries.

Aspell parent directory

The directory path specified here will be used to store the data/dictionary directories related to Aspell. By default this will point to the application install directory. When used from the editor, Aspell looks for dictionaries under the GNU/Aspell directory.
