Access Nested Archive Files

Jul 3, 2014 at 5:13 AM

I want to access a compressed file inside a 7zip file.
Internal archive is very big and i can not open it in a memory stream to access file list inside it.

1-How can i get file list from an archive which is inside another archive?

2-Is there any way to find start position of an entry in archive? so i can ignore other files in archive and move pointer to that place and access that special entry?
