AFAICT, Kobo software loads only the index file into memory (called "words" --- it uses a very efficient data structure, called MARISA trie; its size only depends on the number of words in your dictionaries, not the size/length of the definitions), while it unpacks only the relevant definition file ??.html when the lookup in the index succeeds for the word selected by the user via the UI.

My suggestion is: build your dictionary and see what happens.

Got it. Big thanks for quick reply. I tried to convert dict format to kobo's, the process seems good at the start, but then I come up with that:

C:\Penelope>penelope.py -p zho_rus -f zho -t rus --output-kobo
[INFO] Input dictionary has sequence type 'x'.
[INFO] Starting conversion with the following parameters:

I am using:

Penelope 1.20
Python 2.7.0

What went wrong here and how to fix it?
Thanks.
