The Filebox seems to try to be independent of other system. It uses its own themes in /opt/filebox/icons. However, it's theoretically possible to add your own 'symlink' theme which would add support for current icon theme. There isn't need to read any files for it. EDIT: attached tar.gz After extracting it there should appear a folder /opt/filebox/icons/current full of symlinks And in Filebox settings there should appear one more theme: current Select it, close and open Filebox, and Filebox should use icons from your current Maemo icon theme
