To add a new spelling dictionary to Oxygen or to replace an
existing one you should follow these steps:
Download the archive with the files of your language dictionary.
A dictionary has two files with the same name and different extensions: a file with
.dic extension and a file with .aff
extension.
Copy the .aff and .dic files to the
spell subfolder (.spell subfolder on Linux and
Mac OS X) of the Oxygen
preferences folder only if it is a new dictionary (it is not available as built-in
dictionary in Oxygen).
The Oxygen
preferences folder is [APPLICATION-DATA-FOLDER]/com.oxygenxml.author, where
[APPLICATION-DATA-FOLDER] is:
C:\Documents and Settings\[LOGIN-USER-NAME]\Application Data on
Windows XP
C:\Users\[LOGIN-USER-NAME]\AppData\Roaming on Windows Vista
[USER-HOME-FOLDER]/Library/Preferences on Mac OS X
[USER-HOME-FOLDER] on Linux
Copy the .aff and .dic files into the folder
[Oxygen-install-folder]/dicts only if it is an existing
dictionary.
Restart the application after copying the dictionary files.
