To make a FluentDictionary (dictionary for Fluentizer) you would need to:
1. Download some dictionaries from
http://xdxf.revdanica.com/down/Alternatively, you can make XDXF dictionaries from dictionaries in other formats like Lingvo DSL, StarDict, SDict, dictd and JMdict using makedict
http://xdxf.revdanica.com/forum/viewforum.php?f=28 or JMdict_to_XDXF
http://sourceforge.net/project/showfiles.php?group_id=95155&package_id=253867or any other converter (that can produce XDXF dictionary) at
http://sourceforge.net/project/showfiles.php?group_id=95155 or elsewhere on the internet.
2. Unpack the XDXF dictionaries into a folder. Note that an XDXF dictionary is a folder containing files dict.xdxf and icon16.png
So when you have finished downloading+unpacking or converting -- your current folder should contain folders like eng-rus_muller, eng_rus_full, oxford, eng_eng_main, eng-ch-eng-buddhist or whatever dictionaries you have chosen, each folder containing files dict.xdxf and icon16.png
3. Download XDXF-to-FDK converter from
http://www.fluentizer.com/down/xdxf_to_fdk.jar4. Put xdxf_to_fdk.jar file into the same folder where you have put the XDXF dictionaries. Open a command line window (aka DOS prompt, aka terminal window). Go to the folder where you have put the xdxf_to_fdk.jar file and the XDXF dictionary folders. Enter
java -jar -Xmx500M xdxf_to_fdk.jar
you will see a lot of output as the converter runs, and when it finishes you will have a new file appear in the current folder called eng-rus_xdxf.fdk or eng-chi_xdxf.fdk or something alike depending on the languages (from and to) of the first XDXF dictionary that converter process. Note that the -Xmx500M or larger option is necessary to create any FDK dictionary (except some very small ones) - without this option the converter will run out of memory.
5. Optionally, you can rename the resulted dictionary file into something else, but you have to keep the first 8 chars and the extension intact. For example, you can rename eng-rus_xdxf.fdk to eng-rus_mydictionary.fdk but you can't rename it to mydictionary.fdk because the first 8 chars are used for language identification of the dictionary.
6. Put the resulted FDK dictionary file into the same folder where you have the FluentBooks, and run Fluentizer.
