|---|---|
| The structure of *.lud dictionaries is very simple: word - translation. Lingvo indexes the entire card. | The structure of *.lsd dictionaries is described by means of tags, which are used for text formatting and defining zones in the card. |
| You can add new entries to *.lud dictionaries directly from within ABBYY Lingvo (Tools>Create/Edit Card…). | You cannot add new entries to *.lsd
dictionaries directly from within ABBYY Lingvo. To make changes to the dictionary, you need to change its source code and recompile it. |
| The dictionary comprises three files: *.lud,
*.adx and *.ann. The first two files contain entry headwords and entry bodies respectively. The third file is optional and contains information about the dictionary. |
The dictionary comprises only one file: *.lsd. |
| *.lsd dictionaries take up less disk space. | |
| Information about the dictionary must be typed in an *.ann file, which is then compiled together with the source code of the dictionary. The name of the *.ann file must be the same as the name of the source file. |
