### How to download and install dictionaries

Dictionaries in OmegaT are based on the StarDict Platform. To install the necessary files, proceed as follows:

- Search for the required language combination -for instance on the StartDict Platform above or on FreeDict
- Download the file - it should be a tarball archive (extension tar.bz or tar.bz2).
- Use untar (or equivalent (for instance winrar in Windows) to extract its contents into the project folder "Dictionary". There should be three files, with extensions dict.dz, idx and ifo.

Note that additionally to "source-target" dictionaries you can, via Dictionary, get access to information such as:

- Webster's Revised Unabridged Dictionary (1913)
- Longman Dictionary of Contemporary English
- Merriam Webster 10th dictionary
- The Britannica Concise Encyclopedia
- ...etc

Some of the dictionaries have no strings attached - i.e. are "Free to use", and some of them, like the selection above, are under the GPL license. The following example shows Merriam Webster 10th dictionary "in action":

### Problems with dictionaries

If your Dictionary pane is empty, check the following:

- Are your dict files in the folder (or in one of the subfolders thereof), specified in your Project file? Check in the Project Properties window (menu Project → Properties or `Ctrl+E`)?
- Does the folder contain three files of the same name, with extensions dict.dz, idx and ifo? If there's just one file with the expected name, then check its extension. If it is tar.bz, then you have forgotten to unpack (untar) it.
