I optified the emelfm2 package available on qole's site (0.5.0-rev29) and tweaked the config file for a better gui. The package was somewhat too large so couldn't be attached to the post; it's here.

(I uploaded it on my site with maemoftp which quite luckily works under Maemo5 too . Should someone like an optified version, lacking only some icons which likely came from the maemo4 system, it's here.)
