We have a scenario where we have a hierarchical ZIP structure (ZIPs within ZIPs with ZIPs, etc.) that is flattened into a single ZIP. Every time we encounter a ZIP we copy it out of the archive (typically to a MemoryFile), open it, and copy the files to the destination ZIP. 

However this process takes considerable amount of time to decompress then immediately recompress the data.

Is there a way, possibly through extensions to ZipArchive/Folder/File objects, to bulk copy the compressed data (assuming compatibility) directly from one ZIP to another?

Thanks in advance,

Hi Jason,

There is no faster method to merge two separate zip archives into one. You must uncompressed them and retrieve the data before creating the merged zip archive that will contain both information.
