Hunspell uses these files for vernacular writing systems:
This file stores words that are considered to be correctly spelled.
Words are added when you choose Correct in a Spelling Status field or use Bulk Edit Wordforms to do it.
For the default vernacular writing system, FieldWorks (FLEx) creates the *.dic file (and *.aff file) the first time you select Show Vernacular Spelling Errors. You can create multiple vernacular spelling dictionaries.
In this file, the top line shows the number of words in the file. The second line is for file identification; do not delete or edit it.
exc means exceptions.
This file is created the first time you use Add to Spelling Dictionary for a vernacular word.
This file stores words added with Add to Spelling Dictionary. These are correctly-spelled words that are in addition to those in the *.dic file.
Words move from this file to the *.dic file each time the project is opened.
This file is recreated each time the project opens or you change spelling status with Bulk Edit Wordforms.
*.aff
FLEx creates this file, but is essentially empty. Some advanced users may be able to use this file which would permit the right-click menu to offer corrected words as valid spellings. To learn how, refer to Hunspell documentation at https://manpages.ubuntu.com/.
* is the file name, which tells you the particular language.
OpenOffice/LibreOffice and other programs use hunspell. However, even if one of these programs is installed on your computer, you must copy the *.dic and *.aff files into the hunspell folder so FLEx can access them.
The hunspell folder location:
C:\Users\<username>\AppData\Roaming\hunspell (Windows®)
(Type %AppData% in your Windows® Explorer address bar to get close to the folder.)
home/.config/hunspell (Linux).
Then, open the hunspell folder to see, copy or paste in files.
Select a spelling dictionary with the Spelling dictionary control (General tab of the Writing System Properties dialog box).
Vernacular spelling dictionary files are not included in the backup file because they are stored internally. They are regenerated when you restore the project. You see spelling status selections in Word Analyses.
Before you click Add to Spelling Dictionary, look at the Format toolbar and make sure the correct writing system was used for the flagged word.
The writing system determines which spelling dictionary receives the spelling. (If styles are similar, the writing system may not be obvious.)
