Shareaza

This is a handy option in eMule which allows to first download continous portions at the beginning and the end of the file, which gives instant preview of many ZIP and AVI files which store vital information at the end of the file. After some percentage is completed, chunks are randomized as usual.

AFAIK shareaza already downloads these parts first when they are available

ivan386 already proposed (or even submitted code ?) to give an option for any download to do sequential download of chunk wherever this is possible. But this was rejected on old forums because it hurts already stagnating G2 network

double post, there is no delete opt

I think effective way is beetwen, not all chunks but perhaps some more then now.
And in order considered part from beginnng, end, and random middle.
Of course code could be useful but with adaptations - I was meaning this.
