Hello,
I need help for properly using ZIP library altering ZIP files:
1. I need to dynamically alter compression level of newly added deflated ZIP entries (1 to 9), not only added with maximum compression 9.
I didn't find proper way by using ZipFile class or by ZipOutputStream.
So add a fast patch to ZipFile code, possibly not required.
2. I need to unite contents of other zip file entry by entry (or at least whole) into current ZIP.
Also I didn't find the proper way either by ZipFile or by ZipOutputStream.
3. I need to separately compress data for ZIP file and put data in it.
This means that I want to do generation and compression of file contents in one thread and update zip file in other.
Otherwise I have freezes related to compression of large amount of memory (about 2GB) and require so much memory instead of its compressed equivalent (about 50Mb even in compression level 1).
Could You help me properly use library?
Many thanks.
Regards.
