Hi Rob1n, thanks for your reply. basically i notice that all the dic from this web site:

http://xdxf.revdanica.com/down2/inde...ormat=StarDict

are in the format dict.dz

when i decompress them, in the diretory i can find 3 files, for example:

oxford.dict.dz
oxford.idx
oxford.ifo

is the .index file the .idx file i can see in the uncompressed directory?

I can notice that if i copy the directory on the n900 probably the dictionary is seen by mstardict because i can see an empty space in the list of the dictionary before the dict that have only the .dict extension but that is not possible to use it.

In the case it is in dictd format, it is possible to convert it?

Thanks again

Giorgio
