When you press the Add button during spell check, Infix records the word you are adding in a custom dictionary file on disc.

If you add a word by mistake you can edit the custom dictionary by hand using any standard text editor (such as Notepad).

If you already have a custom dictionary you want Infix to use you can add its contents to Infix’s existing dictionary using a text editor.

Locating the custom dictionary

All of the personal word list files for each language are stored in the same folder. A *.pws file is only created if you have added words during a spell check,.

On Windows XP, the default installation path would be:

C:\Documents and Settings\<username>\Application Data\Aspell\personal

On Windows Vista, Windows 7 and 10:




Format of custom dictionary

The *.pws dictionary file is a simple list of words, each on a new line. An example is shown below:
personal_ws-1.1 es 7

Adstract Technology Iceni

Ltd Bushnell Norwich


The number at the end of the first line is the count of words in the list. The language code is prior to that - in this case ‘es’ for Spanish.

Changes to the custom dictionary will take effect the next time Infix is launched.
