are zips like map files mod files and any outer zips ever exstracted to the filesystem anywhere or are they only ever exstracted in memory?

also what zip library are you using? the licenses page shows you have both minizip and zlib as dependencys

Zip save file contents are only ever extracted into system memory. Other stuff in the zip file might be extracted into the "currently playing" directory.

We use both minizip and zlib. zlib does the inflate/deflate algorithm logic and minizip does the handling of the zip file structure in memory.
