you can edit the dictionary just using notepad. the database is a plain text file ( *.txt )
The database folder is in this path :
64 bit Windows :
C:\Program Files (x86)\Lau Han Ching\TxtReaderXpress\dictionaries\
32 bit Windows :
C:\Program Files\Lau Han Ching\TxtReaderXpress\dictionaries\
Don't mix wordlist database and dictionary database in one folder. dictionary database folder always have a "Dictionary" in the folder name. all text document is save as unicode encoding
