Change spell check language in WPS Office

updated for version 10.1

The extracted directory from downloaded archive (e.g. en_US, fr_FR, etc) can be put in /opt/kingsoft/wps-office/office6/dicts (all users) but also in ~/.kingsoft/office6/dicts (for each user).

Some dictionaries come with improper names. In each language-folder (e.g. fr_FR) the files have to be renamed so the package of each language has (at least) three files with the following names:

• dict.conf

• main.aff

• main.dic

Review --> Spell Check --> Set Language --> Set Default

UPDATE: Ubuntu 18.04 with WPS 10.1, name and location of the dictionaries was not the decisive factor in my case: the new dictionaries would not appear in the list (under Review --> Spell Check --> Set Language --> Set Default) unless they were first added under Review --> Spell Check --> Spell Check --> Custom dictionaries --> Add.

And there added from any location without changing their names - only then resulting in them being listed as indicated initially under Review --> Spell Check --> Set Language --> Set Default.
