Kanema wophatikizikayo ndi woyenera kuyika zida zodzitchinjiriza ndipo amagwiritsidwa ntchito kuzinthu zodzitchinjiriza zokha monga kulongedza chakudya ndi kunyamula chakudya cha ziweto. Ubwino waukulu ndikusunga ndalama.
Palibe tanthauzo lomveka bwino komanso lokhazikika la filimu ya roll mumakampani opanga ma CD. Ndi dzina wamba mu makampani. Mwachidule, kukulunga filimu yolongedza ndi njira imodzi yocheperako kuposa kupanga matumba omalizidwa opanga ma CD. Mtundu wake wazinthu umakhalanso wofanana ndi wamatumba apulasitiki.
