Thx Bike Killa but supposing I decided to split my film in 5 parts and decided to send every part to a temmate, is each teammate able to see that part he has received ?
It seems a little bit difficult to me, each part separated from the other, could loose the reference structure it had while it was joined to the others to composed the entire film so the film viewer could not recognize the structure it is expecting to find (or not ????).
I have tryed to do a thing like you said with another program with no results (anyway it was not WinRAR) but, I will try another time.
