Why is no direct-unpack possible for 7z.001 file structure

[sorryusernameisalreadytaken]

Hey there.

I found out that when I have some nzb's with the file structure:
Ray.x269.7z.001
Ray.x269.7z.002
Ray.x269.7z.003
Ray.x269.7z.004
....

nzbget is not able to do a direct-unpack. Is there any reason for that?

DirectUnpack only works with unrar because it supports streaming extraction (unpacking while downloading).
7zip doesn't support this.

Could you add a mention about this under the DirectUnpack settings?

Yes, sure.
