To customize a Dict file click on the "Open" button, this will show a file dialog with a *.dict filter. Choose the Dict file to customize and click OK. This loads the Dict file and the main text box shows the details of the dictionary.
If you attempt to open a file from a location that Dict Manager does not have permission to write to, you'll receive a 'read only' warning - please restart Dict Manager with Admin privilege.
New Dict files can be created using File->New.
Words can be added or removed one at a time to a Dict file through the lower text field. Words can also be added by merging *.txt or *.dict files, to do this drag and drop the file with the word list on to the main text box.
Saving Dict files requires some processing which may take a few minutes, depending on it's size and disorder.
