Fisoco
a Finding, Sorting and Converting free software (file manipulation)
...You will be able to locate files on the system, to delete them, to move them, to convert them, to rename them, etc.
Fisoco means FInding, SOrting and COnverting. It is perhaps not the final name, but it sounds well to me. Its development is progressing slowly, as the developper learn how does work C++ and gtkmm.
